Duramax 6.6L Fuel Filter Housing — Complete Billet Aluminum Assembly The iFJF 12642623 Fuel Filter Housing Assembly is a complete, ready-to-install billet aluminum fuel filtration unit engineered for 2005-2013 GM Duramax 6.6L V8 diesel engines (LBZ, LLY, LMM). If your factory plastic housing is cracked, leaking, or the primer pump won't hold pressure, this assembly replaces everything in one bolt-on unit — no piecing together parts or reusing degraded components. Duramax owners know the OEM fuel filter housing is a known failure point. Heat cycling causes the plastic body to crack and warp, the primer pump diaphragm deteriorates, and the bleeder screw threads strip — leading to air intrusion, hard starts, rough idle, and potential CP3 injection pump damage. This billet aluminum upgrade eliminates every one of those failure modes permanently. Key Features Complete Bolt-On Assembly: Includes filter head, integrated hand primer pump, WIF sensor port, bleeder screw, and mounting hardware — everything pre-assembled and ready to install Billet Aluminum Construction: CNC-machined from solid 6061-T6 aluminum with corrosion-resistant anodized finish — will never crack, warp, or degrade like factory plastic Direct OEM Replacement: Exact dimensional match for GM part #12642623. Bolts to factory mounting points with no modifications Improved Fuel Flow: Optimized internal passages reduce restriction for better fuel delivery under load and towing conditions Accepts Standard Filters: Compatible with TP3018, TP3012, and 29531007 fuel/water separator elements WIF Sensor Ready: Pre-threaded port accepts your factory water-in-fuel sensor — simply transfer from old housing Vehicle Compatibility Year Make Model Engine 2005-2013 Chevrolet Silverado 2500HD 6.6L Duramax V8 (LBZ, LLY, LMM) 2005-2013 Chevrolet Silverado 3500HD 6.6L Duramax V8 (LBZ, LLY, LMM) 2005-2013 GMC Sierra 2500HD 6.6L Duramax V8 (LBZ, LLY, LMM) 2005-2013 GMC Sierra 3500HD 6.6L Duramax V8 (LBZ, LLY, LMM) Technical Specifications Specification Value Replaces OEM 12642623 Material 6061-T6 Billet Aluminum (Anodized) Filter Thread M36 x 1.5 (standard Duramax spin-on) Inlet/Outlet 1/2" NPT Fuel Compatibility ULSD, B5-B20 Biodiesel WIF Sensor Port Pre-threaded — accepts OEM 12639277 sensor Primer Pump Integrated hand primer (diaphragm type) SKU FJ-TP3018-COMB Installation Tools Needed: 10mm socket, 13mm wrench, flathead screwdriver, diesel-rated thread sealant Time: 30-45 minutes Pro Tip: Lube the filter O-ring with clean diesel before threading on. Use the hand primer until firm — 20-30 pumps typically — before starting the engine Check: Start engine, let idle 2 minutes, inspect all connections for leaks before closing hood FAQ Q: Will this fit my 2008 LMM Duramax? A: Yes. This housing fits all 2005-2013 Duramax 6.6L engines including LBZ, LLY, LMM variants in Silverado and Sierra 2500HD/3500HD. It also fits 2004.5-2005 LLY. If you have a 2001-2004 LB7, check our 12642623 Head + 1R-0750 Kit. Q: What are the signs my fuel filter housing needs replacement? A: Common symptoms: (1) Hard starting after sitting overnight — air is entering the system through a cracked housing or failed primer pump seal; (2) Visible fuel leaks around the housing or bleeder screw; (3) Primer pump won't get firm — diaphragm is torn; (4) "Water in Fuel" light stays on despite draining — sensor port is damaged. Q: Does this come with a new WIF sensor? A: The housing includes a pre-threaded sensor port. You can reuse your existing water-in-fuel sensor. If yours is malfunctioning, we recommend replacing it at the same time for a complete refresh. Q: What's the difference between this and the 12642623 Head + 1R-0750 Kit? A: This is the standard replacement housing — uses factory-style TP3018 spin-on filters. Our 12642623 + 1R-0750 Kit adds a CAT filter adapter for higher flow rates — ideal for tuned trucks and heavy towing. Choose based on your performance needs. Q: Is billet aluminum really better than the OEM plastic housing? A: Absolutely. The OEM plastic housing on Duramax engines is injection-molded nylon that becomes brittle after repeated heat cycles (under-hood temps exceed 200°F). The billet aluminum housing has a coefficient of thermal expansion matched to the engine, won't warp under heat, and the threads won't strip. It's a permanent fix — not a temporary replacement. Q: Can I install this myself? A: Yes — it's a straightforward bolt-on job if you're comfortable with basic hand tools. Disconnect the fuel lines (have rags ready — some fuel will spill), remove 3 mounting bolts, transfer the WIF sensor, bolt the new housing on, reconnect lines, prime the system, and start. Most DIYers complete it in under an hour. See our step-by-step rebuild guide for full instructions. Q: What filter does this use? A: Standard Duramax spin-on fuel filters — TP3018, ACDelco TP3018, TP3012, or 29531007 elements. We stock the TP3018 fuel filter individually and in a combo pack with the 29539579 transmission filter. Q: Do I need to replace the seals on my fuel filter head before installing the new housing? A: This is a brand-new complete housing — all seals are pre-installed. If you're keeping your existing housing and just want to refresh the seals, get our 6-piece rebuild kit instead. Q: What filter does the 12642623 housing use?A: This housing accepts standard Duramax spin-on fuel/water separator filters — specifically the TP3018, TP3012, and 29531007 elements. The TP3018 is the most common replacement (1,300+ monthly searches by Duramax owners), offering 4-micron absolute filtration with hydrophobic water separation media. We stock TP3018 filters individually and in combo packs — see our TP3018 fuel filter for details. Q: Is this compatible with the Duramax fuel filter housing bypass kit?A: No — this is a direct OEM-replacement housing (12642623 spec). If you're looking for a high-flow conversion that accepts CAT 1R-0750 filters (2-micron absolute, lower cost per filter), see our 12642623 + 1R-0750 kit which includes the CAT filter adapter upgrade. 📖 Related Guides Duramax Fuel Filter Housing: Complete Compatibility & Replacement Guide (2001–2024) How-to Replace & Rebuild the Diesel Fuel Filter Head on a Duramax Engine 🔧 Complete Your Fuel System TP3018 Fuel Filter — related Duramax fuel system component Fuel Filter Head Rebuild Kit — related Duramax fuel system component Billet Air Bleeder Screw — related Duramax fuel system component Water in Fuel Sensor — related Duramax fuel system component 12642623 Head + 1R-0750 Kit — related Duramax fuel system component

TP3018 Fuel Filter — Premium Filtration for Duramax 6.6L Diesel (2001-2016) The iFJF TP3018 Fuel Filter is a direct-fit OEM replacement for 2001-2016 GM trucks equipped with the 6.6L Duramax diesel engine. Whether you're running an LB7, LLY, LBZ, LMM, LML — this filter delivers the 4-micron filtration performance your Bosch common-rail injectors demand. A single grain of sand-sized contaminant can score an injector nozzle — this filter prevents that. Available in 1-Pack ($49.99) or 2-Pack ($89.99 — save $10). The TP3018 is one of the most critical maintenance items on any Duramax. GM specifies replacement every 15,000 miles, but many owners change it every other oil change (10,000 miles) for extra protection — especially if you fuel up at high-traffic stations or run biodiesel blends. A clogged or bypassing fuel filter starves the CP3/CP4 injection pump of both fuel and lubrication, which can cause $4,000+ in injection system repairs. Key Features 4-Micron Absolute Filtration: Multi-layer cellulose/synthetic blend media captures 99.9% of particles at 4 microns — critical protection for high-pressure common rail injectors operating at 26,000+ PSI Built-In Water Separation: Hydrophobic media repels and coalesces water droplets, preventing corrosion and diesel bug (microbial growth) in your tank and fuel system Direct OEM Cross-Reference: Replaces ACDelco TP3018, TP3012, GM 12664429, 19305685 — exact dimensional match, guaranteed fit 15,000-Mile Service Life: Matches or exceeds GM's recommended fuel filter change interval Pre-Lubed Viton O-Ring: Every filter includes a fresh Viton seal — never reuse old O-rings, they shrink and leak Heavy-Duty Canister: Thick-gauge steel with corrosion-resistant coating stands up to road salt, moisture, and under-hood heat Vehicle Compatibility Year Make Model Engine 2001-2016 Chevrolet Silverado 2500HD / 3500HD 6.6L Duramax V8 (LB7, LLY, LBZ, LMM, LML) 2007-2016 GMC Sierra 2500HD / 3500HD 6.6L Duramax V8 2012-2016 Chevrolet Express 2500 / 3500 / 4500 6.6L Duramax V8 (LGH/LML) 2012-2016 GMC Savana 2500 / 3500 6.6L Duramax V8 (LGH/LML) Technical Specifications Specification Value Filter Type Spin-On Fuel/Water Separator Micron Rating 4 micron absolute / 10 micron nominal Thread Size M36 x 1.5 Height Approx. 6.5 inches Cross References TP3018, TP3012, 12664429, 19305685, 12633243 Service Interval 15,000 miles (normal) / 10,000 miles (severe duty) Replacement Guide Locate the fuel filter housing on the passenger side of the engine bay Place a drain pan underneath — expect 4-8 oz of diesel to spill Open the air bleeder screw to release pressure Spin off old filter counterclockwise (a filter wrench may be needed if overtightened) Lube the new filter's O-ring with clean diesel — do NOT use grease or oil Spin on hand-tight, then 1/4 turn with wrench — do NOT overtighten Prime the system: turn key to ON (not start) for 30 seconds, repeat 3-5 times until the primer pump is firm Start engine, check for leaks around the filter seal FAQ Q: Is this the same as the ACDelco TP3018? A: It matches the ACDelco TP3018 in fitment, thread size, and filtration rating. Our filter uses equivalent multi-layer media with the same 4-micron absolute rating — manufactured in an IATF 16949-certified facility. You get OEM-equivalent protection at aftermarket pricing. Q: What happens if I don't change my fuel filter on time? A: A clogged fuel filter restricts fuel flow to the injection pump. Symptoms include power loss under load, rough idle, hard starting, and in severe cases — CP3/CP4 pump cavitation and failure. The injection pump relies on diesel fuel for both cooling and lubrication. A restricted filter starves it of both. Injector replacement on a Duramax costs $3,000-$5,000. A $49.99 filter is cheap insurance. Q: Will this fit my 2001 LB7? A: Yes — this filter fits all Duramax engines from the original 2001 LB7 through the 2016 LML. The filter thread (M36 x 1.5) has been standard across all generations. Q: Can I use this filter with biodiesel (B5-B20)? A: Yes, compatible with ULSD and biodiesel blends up to B20. Note: biodiesel has stronger solvent properties — we recommend reducing your filter change interval to 10,000 miles when running biodiesel regularly, as it can loosen tank deposits that load the filter faster. Q: Why does my truck feel sluggish after the filter change? A: You likely have air in the system. Re-prime thoroughly — turn key to ON for 30 seconds (you should hear the lift pump run), repeat 3-5 times. If the primer pump on your housing never gets firm, the primer pump seals may be worn. Q: What's the difference between your TP3018 and the WIX equivalent? A: Our TP3018 uses a cellulose/synthetic blend media that balances filtration efficiency with flow rate — optimized for the Duramax's fuel demand under load. WIX 33960XE uses a full synthetic media. Both are quality filters; ours is priced $10-15 less per unit. Q: Should I buy the 2-pack? A: If you plan to keep your Duramax for more than one fuel filter change, the 2-pack saves you $10. Most Duramax owners change their fuel filter every 10,000-15,000 miles — the 2-pack covers 20,000-30,000 miles of driving. Keep the spare on your garage shelf. Q: Why is the TP3018 the most popular Duramax fuel filter?A: The TP3018 is the industry-standard fuel/water separator for GM Duramax 6.6L engines — with 1,300+ monthly searches and a 15.2% purchase rate among Duramax owners actively shopping. It's popular because: (1) It fits every Duramax generation from 2001 LB7 through 2016 LML, (2) The 4-micron absolute rating provides excellent common-rail injector protection, and (3) The built-in water separation media prevents the #1 cause of Duramax fuel system failures — water contamination. Every Duramax owner should keep a spare on the shelf. Q: What's the difference between TP3018 and TP3012?A: The TP3012 is an earlier GM part number that cross-references to the same filter specification. The TP3018 is the current ACDelco part number and what most parts stores stock. Both fit the same M36 x 1.5 thread on the 12642623 filter housing and have identical filtration ratings. Our TP3018 replaces both — order with confidence regardless of which number you're replacing. 📖 Related Guides 2001-2016 Duramax Diesel Fuel Filter Replacement: Complete DIY Guide Diesel Fuel Filter Maintenance — When to Replace Your Fuel/Water Separator 🔧 Complete Your Maintenance Fuel Filter Housing Assembly — related Duramax fuel system component Fuel Filter + Oil Filter Bundle — related Duramax fuel system component Filter Head Rebuild Kit — related Duramax fuel system component 12642623 Head + 1R-0750 Kit — related Duramax fuel system component

Duramax Fuel Filter Head Rebuild Kit — Stop Leaks & Hard Starts The iFJF Duramax Fuel Filter Head Rebuild Kit fixes the most common fuel system issues on 2001-2013 GM Duramax 6.6L diesel trucks (LB7, LLY, LBZ, LMM) — fuel leaks, air intrusion, and a primer pump that won't hold pressure. This 6-piece Viton seal kit replaces every wearable seal and O-ring in your filter head, plus includes a CNC-machined billet aluminum bleeder screw to replace the notoriously failure-prone OEM plastic screw. Save $200+ compared to replacing the entire filter housing at the dealer. Over time, the rubber seals in the Duramax filter head harden, shrink, and crack from heat cycling and diesel exposure. When seals fail, air enters the fuel system — causing extended cranking on cold starts, rough idle, and stalling under load. The OEM plastic bleeder screw is another known weak point: the hex head rounds off and the threads strip after just a few filter changes. This kit solves both problems in one affordable package. What's Included 6 Viton O-Rings & Seals: Primer pump diaphragm seal, filter head base gasket, heater element O-ring, WIF sensor O-ring, bleeder screw O-ring, and fuel line fitting seal — all Viton for superior diesel and heat resistance CNC Billet Aluminum Bleeder Screw (Black): Replaces the OEM plastic bleeder screw (GM 97363195). Machined from solid 6061-T6 aluminum — will never strip, crack, or round off Installation Guide: Step-by-step instructions with torque specs for each seal Key Features Viton Material: Unlike generic rubber O-rings that degrade in diesel within months, Viton (FKM) seals resist diesel fuel, biodiesel, engine heat (rated to 400°F), and compression set — maintaining a leak-free seal for years Complete Kit: Every seal you need — no running to the parts store mid-job for that one O-ring you forgot Billet Bleeder Screw: Same 6061-T6 aluminum construction as our standalone billet bleeder screw — solves the stripped-thread problem permanently Dealer Alternative: GM dealers typically replace the entire filter housing ($300+) instead of rebuilding it. This $23.99 kit fixes the actual problem. Compatibility Year Make Model Engine 2001-2013 Chevrolet Silverado 2500HD / 3500HD 6.6L Duramax (LB7, LLY, LBZ, LMM) 2001-2013 GMC Sierra 2500HD / 3500HD 6.6L Duramax (LB7, LLY, LBZ, LMM) When to Rebuild Your Filter Head Primer pump never gets firm — stays soft even after 20+ pumps Hard starting after truck sits overnight (air in fuel system) Visible diesel residue around the filter head or bleeder screw "Water in Fuel" light flickers intermittently (sensor O-ring leak) Fuel drips from the bottom of the housing after filter change FAQ Q: Is this a difficult DIY job? A: Moderate difficulty — expect 1-2 hours. You'll need basic hand tools (10mm socket, pick set for old O-rings, torque wrench). The filter head stays on the engine — you're just replacing seals. Our step-by-step rebuild guide walks you through every step. Q: Will this fix my hard start problem? A: If your hard starts are caused by air intrusion through worn seals — very likely. After the truck sits, air replaces fuel in the filter head. When you crank, the injection pump has to push that air pocket through before fuel reaches the injectors. New seals prevent air from entering. If hard starts persist after rebuild, check the fuel pressure regulator and injection pump. Q: What's the difference between this and buying a whole new housing? A: A new fuel filter housing assembly ($97.99) replaces everything — housing, primer pump, and all seals. This rebuild kit ($23.99) replaces the seals and bleeder screw only — ideal if your housing body is physically intact but the seals are leaking. If your housing is cracked or the primer pump lever is broken, get the full housing. Q: Are these seals diesel-proof? A: Yes — Viton (FKM) is the gold standard for diesel fuel systems. Unlike standard nitrile (Buna-N) O-rings that swell and degrade in diesel, Viton maintains its shape and elasticity at temperatures up to 400°F. These are the same material used in OEM Cummins and Duramax fuel system seals. Q: Can I install the billet bleeder screw separately? A: Yes — if you only need the bleeder screw, get our standalone billet aluminum bleeder screw (available in red, black, and silver). Q: What torque should I use on the bleeder screw? A: Hand-tighten, then 1/8 turn with a wrench. The O-ring does the sealing — overtightening damages threads. The billet aluminum screw has much stronger threads than the OEM plastic — but the housing threads are still aluminum. Snug is enough. Q: When should I rebuild vs. replace my Duramax fuel filter head?A: Rebuild if: the housing body is physically intact with no cracks, and the problem is leaking seals, a soft primer pump, or a stripped bleeder screw — this $23.99 kit fixes all three. Replace the entire housing if: the housing body is cracked, the mounting tabs are broken, or the primer pump lever is physically damaged.

Billet Aluminum Air Bleeder Screw — Permanent Fix for Duramax Fuel Filter Housing If you've changed a fuel filter on a Duramax, you already know: the OEM plastic bleeder screw is a disaster waiting to happen. It strips, the hex head rounds off, and eventually it either seizes or breaks — leaving you stranded with a fuel system full of air and no way to bleed it. The iFJF Billet Aluminum Air Bleeder Screw (Red Anodized) replaces that weak link with a CNC-machined 6061-T6 aluminum upgrade that will outlast your truck. Compatible with 2001-2017 GM Duramax 6.6L diesel fuel filter housings (LB7, LLY, LBZ, LMM, LML), this screw threads directly into the factory bleeder port with zero modifications. The precision-cut threads match the housing perfectly — no cross-threading, no leaks. The red anodized finish adds corrosion resistance and a clean under-hood look. Key Features 6061-T6 Billet Aluminum: Machined from a solid block of aircraft-grade aluminum — the hex head won't round off, the threads won't crack under heat and pressure Perfect OEM Thread Match: Threads precision-cut to match GM fuel filter housing specs — clean, leak-free fit every time Universal Duramax Fitment: Fits all 2001-2017 Duramax fuel filter housings including LB7 (2001-2004), LLY (2004.5-2005), LBZ (2006-2007), LMM (2007.5-2010), and LML (2011-2017) Replaces OEM: GM 97363195, GM 513081000 Red Anodized Finish: Corrosion-resistant, looks great under the hood, and easy to spot when bleeding the filter 5-Minute Install: Unscrew old plastic screw, insert new O-ring, thread in billet screw — done Technical Specifications Specification Value Material 6061-T6 Billet Aluminum Finish Red Anodized (Type II) Thread OEM-matched (GM spec) Replaces GM 97363195, 513081000 SKU FJ-AD04-RD FAQ Q: What makes this better than the OEM plastic screw? A: Three things: (1) Material — billet aluminum vs. injection-molded nylon. The OEM screw hex head rounds off after 2-3 filter changes because plastic deforms under torque. (2) Thread strength — aluminum threads don't crack when the housing expands from heat. (3) Heat resistance — the OEM plastic screw softens at under-hood temperatures, which causes it to seize in the housing. Q: Will this fit my 2014 LML? A: Yes. The bleeder screw thread has been consistent across all Duramax filter housings from 2001 through 2017 (LB7 through LML). GM used the same basic filter housing design for 17 model years. Q: Do I need a new O-ring? A: Our bleeder screw includes a fresh Viton O-ring pre-installed. If you're rebuilding the entire filter head, get our 6-piece rebuild kit which includes this screw + all housing seals. Q: Can I overtighten this? A: Hand-tighten, then 1/8 turn with a wrench. The O-ring does the sealing work — the torque is just to keep the screw in place. Unlike the plastic screw, this won't strip from moderate torque, but don't crank on it either. Q: Will the anodizing fade over time? A: Type II anodizing is highly UV and chemical resistant. Under normal under-hood conditions, the red color will maintain its appearance for years. Diesel fuel and engine degreasers won't affect the finish. Q: Does this fit all Duramax fuel filter housings?A: Yes — the GM fuel filter housing bleeder screw thread has been consistent across every Duramax generation from 2001 through 2017 (LB7, LLY, LBZ, LMM, and LML). Over 2,700 Duramax owners search for related parts monthly, making this one of the most common upgrades. Whether you have an early LB7 or a late-model LML, this billet screw threads directly into the factory bleeder port with no modifications. If you're also replacing the housing seals, get our rebuild kit which includes this bleeder screw + all 6 seals. Q: Why billet aluminum over the OEM plastic bleeder screw?A: The OEM plastic bleeder screw (GM 97363195) is injection-molded nylon that has three known failure modes: (1) The hex head rounds off after 2-3 filter changes because nylon deforms under torque, (2) The threads crack when the aluminum housing thermally expands — nylon and aluminum have different expansion rates, and (3) Heat cycling makes the plastic brittle — under-hood temps on a Duramax routinely exceed 200°F. Our 6061-T6 billet aluminum screw is CNC-machined from solid stock with a Type II anodized finish — the threads match the housing's thermal expansion, the hex head won't round off, and it includes a pre-installed Viton O-ring rated to 400°F. Install once and never touch it again. 📖 Related Guides How-to Replace & Rebuild the Diesel Fuel Filter Head on a Duramax Engine 🔧 Related Products Fuel Filter Housing — related Duramax fuel system component Filter Head Rebuild Kit — related Duramax fuel system component

The black anodized cap is understated, corrosion-proof, and will never crack — unlike the OEM nylon plastic cap that GM themselves have documented as a failure point. ⚫ Black vs. Silver — Same Cap, Different Vibe We offer the 134001 billet cap in five anodized colors. The Black finish is the choice for: Stealth / OEM+ builds — looks like it belongs there. Most techs won't notice it's not stock until they grab a socket. Dark engine bay aesthetics — matches factory black trim, hoses, and airbox. Corrosion resistance — Type II anodizing creates a hard aluminum oxide layer that won't flake, fade, or rust, even with road salt and diesel splash. Resale-conscious owners — looks stock enough that no buyer is going to question it, but the next owner will thank you. Prefer a brighter look? Check out our Silver Cap Kit — same internals, polished machined finish. 📊 iFJF Billet Cap vs. OEM Plastic Cap Specification iFJF 134001 (Black) OEM (ACDelco) Cap Material 6061-T6 Billet Aluminum Nylon Plastic Finish Black Type II Anodized Unfinished Black Plastic Hex Size 32mm — Standard Socket 32mm (Plastic) Torque Spec 25 ± 3 N·m (18 ± 2 ft-lbs) 25 N·m (prone to cracking) Crack Resistance ✅ Won't Crack.

LUBE THE O-RINGS: Apply a thin film of clean diesel or silicone grease to both O-rings before installation. Dry O-rings can roll, pinch, or tear — causing hard starts and air in the fuel system. TORQUE TO SPEC: Hand-tighten, then torque to 18 ft-lbs (25 N·m). The billet cap threads engage smoothly — if you feel any resistance, back off and realign. BLEED THE SYSTEM: After installation, cycle the key to "ON" (without starting) 3–5 times to prime the fuel system. The CP4.2 is self-priming — you'll hear the in-tank pump cycle. CHECK FOR LEAKS: Start the engine and inspect the cap area. No drips = good to go. ❓ FAQ Q: What's the difference between the Black Cap and Silver Cap kits? A: Only the anodized finish color. Both caps are CNC-machined from the same 6061-T6 billet aluminum. Both use the same TP1015 filter and Viton O-rings. Both carry the same $69.99 price. Choose Black for a stealth/OEM+ look, Silver for a polished machined finish. Performance is identical. Q: Will the black anodizing wear off over time? A: No. Type II (sulfuric acid) anodizing converts the aluminum surface into a hard aluminum oxide layer — it's not a coating or paint that can flake off. It resists diesel fuel, engine degreasers, road salt, and UV exposure. The only thing that will mar it is a slipped wrench — so use a properly sized 32mm socket. Q: Can I reuse the billet cap with future filter changes? A: Absolutely. The 6061-T6 cap is a lifetime upgrade. At each service interval, you only need to replace the filter element and O-rings. Grab our TP1015 filter-only replacement for $17.99 and keep the black cap in service indefinitely. Q: Will this aftermarket kit void my warranty? A: No. Under the Magnuson-Moss Warranty Act, using aftermarket parts does not automatically void your warranty. The iFJF TP1015 filter meets or exceeds all OEM filtration specifications, and the billet cap is an upgrade over a known failure-prone OEM component (documented in GM TSB #18-NA-103). 🛒 Related Products Prefer a brighter finish?

4" DPF & CAT Delete Exhaust Pipe for 2015-2016 6.6L Duramax LML Turbo Diesel Unlock the full potential of your 2015-2016 Chevrolet Silverado or GMC Sierra 2500HD/3500HD with the 6.6L Duramax LML Turbo Diesel using this 4" mandrel-bent DPF and CAT delete pipe. The factory emissions system – including the Diesel Particulate Filter (DPF) and Diesel Oxidation Catalyst (DOC/CAT) – creates substantial exhaust backpressure that robs horsepower, fuel economy, and reliability. This single-piece delete pipe replaces both restrictive components with a free-flowing 4" mandrel-bent exhaust. Why Delete Your LML DPF & CAT? Excessive Backpressure: DPF + CAT create significant restriction, increasing EGTs and limiting performance. Fuel Dilution During Regen: Active regeneration injects raw diesel during exhaust stroke, contaminating engine oil. Poor Fuel Economy: Regeneration burns extra fuel. DPF restriction reduces efficiency. Owners see 2-4 MPG improvement. CP4 Injection Pump Risk: DPF regeneration cycles contribute to fuel system stress on the already-sensitive CP4 high-pressure pump. Regen Failures: Incomplete regeneration cycles lead to plugged DPF requiring $2,500+ replacement. What's Included Component Material Function 4" DPF/CAT Delete Pipe T409 Mandrel-Bent Stainless Steel Replaces factory DPF and DOC in one piece 3-Hole Turbo Flange CNC Laser-Cut Steel Factory-fit connection at turbo outlet Mounting Hardware & Clamps Grade 10.9 Steel Complete hardware kit for bolt-on installation Vehicle Compatibility Year Make Model Engine 2015-2016 Chevrolet / GMC Silverado 2500HD / Sierra 2500HD 6.6L Duramax LML V8 Turbo Diesel 2015-2016 Chevrolet / GMC Silverado 3500HD / Sierra 3500HD 6.6L Duramax LML V8 Turbo Diesel Performance Benefits +20-30 HP / +40-60 lb-ft: Eliminated DPF/CAT backpressure frees significant power. 2-4 MPG Improvement: No regen fuel waste, improved combustion efficiency. 100-200°F Lower EGTs: Critical for towing safety on long grades. Faster Turbo Response: Reduced backpressure equals quicker spool. Aggressive straight-pipe diesel sound. Installation Overview This system is engineered for bolt-on installation. All factory hanger points are used. Estimated installation time: 2-4 hours with basic hand tools, an exhaust cutter or saw, and a floor jack or lift. No welding required. Frequently Asked Questions Q: Will this fit my 2016 Silverado 3500HD Duramax?A: Yes. This kit is designed for all 2015-2016 Chevrolet Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD with the 6.6L Duramax LML engine. All cab and bed configurations supported. Q: Do I need a tuner after installation?A: Yes. The factory ECM will detect DPF and CAT removal. A compatible tuner is required to disable DPF-related functions and optimize engine calibration. Q: Is this a complete bolt-on kit?A: Yes. All pipes, flanges, clamps, and hardware are included. No additional parts or fabrication required. Q: What's the difference between the muffler and no-muffler versions?A: The muffler version includes a straight-through performance muffler that provides a deep, aggressive tone while controlling in-cab drone. The no-muffler version produces a louder, more aggressive straight-pipe sound. Both deliver identical performance gains. Q: Will my CP4 injection pump be affected?A: Eliminating DPF regeneration cycles reduces stress on the fuel system. While this doesn't directly prevent CP4 failure, many owners report improved long-term reliability after removing the regeneration system. Q: Is this product emissions-compliant?A: This product is designed for off-road and competition use only. Not intended for use on emissions-regulated vehicles. Check local laws before purchase.

Complete EGR Valve & Cooler Delete Kit for 2006-2007 GM Duramax LBZ 6.6L Diesel This comprehensive EGR delete kit completely removes the failure-prone EGR valve and EGR cooler assembly from your 2006-2007 Chevrolet Silverado or GMC Sierra equipped with the legendary 6.6L Duramax LBZ diesel engine. The LBZ's EGR system is a known weak point — cooler failures can lead to catastrophic coolant loss, hydrolock, and engine damage. This kit eliminates that risk permanently while improving airflow, reducing intake temperatures, and simplifying the engine bay. ⚠️ OFF-ROAD USE ONLY: This product is intended solely for off-road, racing, and competition vehicles not operated on public highways. Removing or tampering with emissions control equipment is prohibited by federal law for on-highway vehicles. Verify local regulations before purchasing. Key Features Complete System Removal: Includes blocker plate, coolant bypass fittings, intake manifold block-off, and all required hardware — removes both EGR valve and cooler Billet Aluminum Up-Pipe Block-Off: CNC-machined 6061-T6 aluminum block-off replaces EGR feed from passenger side up-pipe — zero exhaust gas reaches the intake Coolant Reroute Kit: Includes brass hose barb and high-temperature silicone cap to properly bypass EGR cooler coolant circuit without restricting heater core flow Prevents Catastrophic Engine Failure: LBZ EGR coolers are known to rupture internally, dumping coolant directly into the intake — this kit eliminates that failure mode entirely Improved Throttle Response: Removing EGR reduces intake air temperature by up to 100°F, increasing air density and improving combustion efficiency Compatibility Year Make Model Engine 2006-2007 Chevrolet Silverado 2500HD/3500HD (Classic) 6.6L Duramax LBZ (RPO: LLY/LBZ) 2006-2007 GMC Sierra 2500HD/3500HD (Classic) 6.6L Duramax LBZ (RPO: LLY/LBZ) Technical Specifications Component Material Detail EGR Blocker Plate 304 Stainless Steel 3mm thick, laser-cut to port Up-Pipe Block-Off 6061-T6 Billet Aluminum CNC-machined with O-ring groove Coolant Bypass Fitting Brass 3/4 inch hose barb Silicone Cap High-Temp Silicone Rated 400°F continuous Intake Block-Off 304 Stainless Steel Precision-fit with gasket Why Delete the LBZ EGR System? The Duramax LBZ is widely considered the best pre-emissions Duramax engine — but the EGR system is its weak link. When the EGR cooler fails internally (common on high-mileage LBZs), coolant is drawn directly into the intake manifold. Best case: white smoke and coolant loss. Worst case: hydrolock bends a connecting rod. This kit permanently removes that failure mode. Your LBZ will run cleaner, cooler, and more reliably for the long haul. Frequently Asked Questions Q: Does this require an ECU tune to prevent check engine light?A: Yes. Removing EGR triggers DTCs P0401-P0406. A custom ECU tune disabling EGR-related DTCs is required to prevent CEL and limp mode. EFILive and HP Tuners support this modification. Q: Will this affect my cooling system?A: No. The kit includes a coolant bypass fitting maintaining proper flow through the heater core circuit. EGR cooler is isolated without restricting flow to other components. Q: How long does installation take?A: Plan 4-6 hours for first-time DIY. Hardest part is accessing EGR cooler bolts on passenger side. Professional shops typically complete in 3-4 hours. Q: Does this fit the LLY (2004.5-2005) Duramax?A: No, this kit is specific to 2006-2007 LBZ. The 2004.5-2005 LLY uses a different EGR cooler design and up-pipe configuration. Verify engine RPO code before ordering. Q: What tools do I need?A: Metric socket set (8mm-15mm), extensions and swivel adapters, torque wrench, flathead screwdriver, hose clamp pliers, coolant catch pan. 📚 Related Guides & Articles Chevy/GMC Exhaust Header Buyer's Guide SBC vs LS Engine: Header Upgrade Guide Dodge Ram Exhaust Header Installation Guide Mopar 5.2L 5.9L V8 Header Upgrade

iFJF 97363195 Billet Aluminum Air Bleeder Screw — GM Duramax Diesel 2001-2017 The factory plastic air bleeder screw on your GM Duramax fuel filter housing is a ticking time bomb. After years of heat cycling, diesel exposure, and repeated use during filter changes, that threaded plastic piece either strips its hex head, cracks along the threads, or snaps off entirely — leaving you stranded with air in the fuel system. The iFJF 97363195 billet aluminum bleeder screw is the permanent fix. CNC-machined from solid 6061 aluminum, it installs in 5 minutes and will never strip, crack, or fail. Key Features & Benefits Billet Aluminum — No More Plastic Failures CNC-machined from a single block of 6061-T6 aluminum, this bleeder screw is virtually indestructible compared to the OEM plastic part. The hex head won't round off, the threads won't crack under pressure, and the O-ring seat maintains a perfect seal for years. Precision Thread Match Threads are machined to the exact OEM specification for a perfect fit in the fuel filter housing. No thread locker, no sealant — just screw it in, snug it down, and bleed the air like normal. The O-ring groove is cut to the correct depth for reliable sealing. 5-Minute Installation No special tools, no fuel system disassembly, no modifications. Unscrew the old plastic bleeder (if it hasn't already broken), transfer or replace the O-ring, and install the iFJF aluminum screw. Done. A small upgrade that prevents a big headache. Technical Specifications Specification Detail Model iFJF 97363195 Replaces OEM GM 97363195, 513081000 Material 6061-T6 Billet Aluminum Finish Anodized Black Fitment 2001-2017 GM Duramax 6.6L Diesel Hex Size Standard 3/8" or 10mm Socket Compatible Vehicles 2001-2017 Chevrolet Silverado 2500HD / 3500HD 6.6L Duramax 2001-2017 GMC Sierra 2500HD / 3500HD 6.6L Duramax Chevrolet Express / GMC Savana 2500-4500 Duramax Chevrolet Kodiak / GMC TopKick 6.6L Buick, Cadillac, Hummer H1, Saturn, Pontiac with Duramax 6.6L Installation Locate the air bleeder screw on top of the fuel filter housing (black plastic knob with a hex head). Using a socket or wrench, carefully unscrew the old bleeder screw. If it's already broken, use an easy-out or carefully pry out the remaining plastic threads. Clean the threaded hole with a rag or compressed air to remove any plastic debris. Check the O-ring on the new bleeder screw. Install into the housing and tighten to snug — do not overtighten aluminum threads into the plastic housing. Prime the fuel system using the priming pump on the filter housing. Open the bleeder screw slightly until fuel (not air) comes out. Close and continue priming. Start the engine and verify no fuel leaks around the bleeder screw. Why iFJF? We understand the pain of a failed bleeder screw — many of us have been there ourselves. That's why iFJF Direct manufactures this part from real billet aluminum, not cast or injection-molded materials. It's a small part that makes a real difference in reliability. Ships fast from our US warehouse. Frequently Asked Questions Will this fit the L5P (2017+) Duramax? The L5P Duramax (2017-2019 Silverado/Sierra HD) uses a different fuel filter housing design. This bleeder screw is compatible with 2001-2017 models, covering LB7, LLY, LBZ, and LMM engine codes. Verify your filter housing type before ordering. My plastic bleeder is already broken. Can I still install this? Yes. If the plastic screw head has snapped off but the threaded body is intact, use a small flathead screwdriver or an easy-out to remove the remaining piece. If threads are left in the housing, carefully pick them out. The aluminum replacement threads into the same clean hole. Do I need to use thread sealant? No. The bleeder screw seals with an O-ring at the base, not on the threads. Thread sealant or tape is not required and may interfere with the O-ring sealing surface. Just install snug and flush. Can I overtighten this and damage the housing? Yes — the filter housing is plastic. The billet aluminum screw is much stronger. Tighten to "snug plus a little" — roughly 25-30 inch-pounds. You'll feel the O-ring compress. Over-tightening can crack the plastic housing.

This kit combines two essential L5P upgrades — a 3.5" mandrel-bent turbo downpipe and a complete EGR cooler & valve delete kit — into one complete package. Address both exhaust restriction and intake contamination simultaneously for maximum performance gains and long-term engine reliability. Package Contents 3.5" Turbo Downpipe T409 mandrel-bent stainless steel — maintains full 3.5" internal diameter V-band turbo flange for precision leak-free connection OEM hanger points — true bolt-on installation Replaces restrictive factory flattened downpipe 30-50% backpressure reduction at turbo outlet EGR Cooler & Valve Delete Kit CNC-machined 6061-T6 billet aluminum construction EGR cooler block-off plates (intake + exhaust sides) EGR valve delete plate with OEM-spec MLS gaskets Coolant reroute fittings — proper flow path maintained Complete Grade 10.9 hardware kit included Vehicle Compatibility Year Make Model Engine 2017-2023 Chevrolet / GMC Silverado 2500HD / Sierra 2500HD 6.6L Duramax L5P V8 Turbo Diesel 2017-2023 Chevrolet / GMC Silverado 3500HD / Sierra 3500HD 6.6L Duramax L5P V8 Turbo Diesel Why This Combo Package? The L5P Duramax has two critical factory restrictions that limit performance and reliability: the pinched downpipe creating excessive turbo backpressure, and the EGR system causing progressive intake carbon fouling. Addressing either alone provides benefits, but addressing both simultaneously delivers transformative results: Unrestricted Exhaust Flow: 3.5" mandrel-bent downpipe eliminates the single most restrictive point in the L5P exhaust — the flattened factory downpipe. Clean Intake Air: EGR delete prevents carbon accumulation on intake valves, swirl flaps, and manifold — preserving airflow and power for the life of the engine. Synergistic Gains: Cleaner intake charge + freer exhaust flow = 25-40 HP combined potential with supporting calibration. Maximum Reliability: Eliminates both EGR cooler failure risk (coolant in cylinders) and high-EGT conditions caused by exhaust restriction. Cost-Effective: Bundle pricing saves 15-20% compared to purchasing downpipe and EGR delete kit separately. Premium Build Quality T409 Stainless Steel Downpipe: Mandrel-bent for consistent internal diameter — no crush bends, no flow restrictions. CNC Billet 6061-T6 Aluminum EGR Plates: Precision-machined for exact L5P port matching. Anodized finish for corrosion resistance. MLS (Multi-Layer Steel) Gaskets: Rated for L5P boost pressures exceeding 35 PSI — no leaks, no failures. Grade 10.9 Mounting Hardware: High-tensile fasteners engineered for diesel vibration and thermal cycling. Performance Benefits +25-40 HP / +50-80 lb-ft Torque: Combined effect of reduced backpressure and clean intake air with proper tuning. 100-200°F Lower EGTs: Critical safety improvement for towing heavy loads up long grades. Faster Turbo Spool: Immediate throttle response improvement from reduced exhaust restriction. Eliminated Carbon Buildup: No more EGR soot fouling intake valves and manifold — preserved airflow forever. No Coolant Loss Risk: EGR cooler failure permanently eliminated — protects head gaskets and rotating assembly. 1-3 MPG Fuel Economy Gain: Combined efficiency improvement from both modifications. Installation Overview This comprehensive package requires significant disassembly — the downpipe is accessed from underneath, while EGR delete requires intake manifold removal from above. Estimated total installation time: 8-12 hours. Professional installation strongly recommended. Compatible tuning solution required for EGR delete function. All necessary hardware, gaskets, clamps, and fittings are included. No welding or permanent modifications needed. Frequently Asked Questions Q: Will this fit my 2020 Silverado 3500HD L5P?A: Yes. This combo kit fits all 2017-2023 Chevrolet Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD with the 6.6L Duramax L5P engine. All cab and bed configurations supported. Q: Do I need a tuner with this kit?A: Yes. A compatible tuning solution is required to disable EGR-related DTCs and optimize engine parameters for the modified exhaust and intake configuration. For maximum performance benefit, a comprehensive tune addressing both modifications is recommended. Q: Can the downpipe and EGR delete be installed at different times?A: Yes, each component can be installed independently. However, installing both simultaneously saves significant labor time since the intake removal (for EGR) and under-vehicle access (for downpipe) involve related disassembly steps. Most shops recommend doing both at once. Q: Is this kit reversible?A: Both the downpipe and EGR delete kit are bolt-on designs with no cutting, welding, or permanent modifications. The factory components can be reinstalled. Tuning will need to be restored to stock as well. Q: How does this compare to buying the downpipe and EGR delete separately?A: The combo kit provides identical components at a bundled price — typically 15-20% savings versus purchasing individually. All hardware, gaskets, and fittings are identical to the standalone kits. Q: Will I need a wheel alignment after installation?A: No — neither the downpipe nor the EGR delete kit affect suspension geometry. A wheel alignment is not required.
