12642623 Fuel Filter Head Kit + 1R-0750 CAT Filter Adapter — Duramax 6.6L The 12642623 Fuel Filter Head Kit with 1R-0750 Refit Head is the ultimate fuel filtration upgrade for 2005-2016 GM Duramax 6.6L diesel trucks (LLY, LBZ, LMM, LML). This comprehensive package includes two components that address the biggest weaknesses of the factory fuel system: 12642623 Billet Aluminum Filter Head — replaces the failure-prone plastic housing with a CNC-machined aluminum unit including an integrated hand primer pump and heater element 1R-0750 Refit Adapter — converts your filter head to accept high-flow, lower-cost Caterpillar 1R-0750 spin-on filter elements (2-micron absolute filtration, $12-15 each) Why the 1R-0750 conversion? The CAT 1R-0750 filter is widely regarded as the best spin-on fuel filter available — with 2-micron absolute filtration (vs. 4-micron for the standard TP3018), higher flow capacity, and availability at any heavy equipment dealer or truck stop across North America. This conversion has been a popular Duramax modification for over 15 years. Key Features Billet Aluminum Filter Head: CNC-machined from solid 6061-T6 aluminum with electrophoresis coating — will never crack, warp, or leak like the OEM plastic housing 1R-0750 CAT Filter Adapter: Precision-machined black anodized aluminum adapter that bolts to the 12642623 head — accepts standard CAT 1R-0750 filters Integrated Hand Primer Pump: Built-in iron-body primer pump for bleeding the system after filter changes Heater Element Included: Pre-installed fuel heater for cold-weather operation Upgraded Bleeder Screw: Aluminum bleeder screw replaces the OEM plastic screw Complete Hardware Kit: Includes mounting bolts, O-rings, and adapter hardware — everything needed for installation Vehicle Compatibility Make Model Year Engine Chevrolet Silverado 2500HD 2005-2016 6.6L Duramax (LLY, LBZ, LMM, LML) Chevrolet Silverado 3500HD 2005-2016 6.6L Duramax (LLY, LBZ, LMM, LML) GMC Sierra 2500HD 2005-2016 6.6L Duramax (LLY, LBZ, LMM, LML) GMC Sierra 3500HD 2005-2016 6.6L Duramax (LLY, LBZ, LMM, LML) CAT 1R-0750 Filter Advantages Feature Standard TP3018 CAT 1R-0750 Filtration Rating 4 micron absolute 2 micron absolute Water Separation Standard Advanced AquaBlock media Flow Rate Standard Higher — supports tuned engines Availability Auto parts stores Any CAT dealer, truck stop, Amazon Typical Price $25-35 $12-18 Service Life 15,000 miles 15,000 miles FAQ Q: Is this different from the standard 12642623 housing? A: Yes — this kit includes the 12642623 billet filter head plus the 1R-0750 refit adapter. The standard 12642623 housing uses factory-style TP3018 filters. This kit converts to CAT 1R-0750 filters for 2-micron filtration and lower filter costs. Choose based on your filtration and budget priorities. Q: Where do I buy CAT 1R-0750 replacement filters? A: Any Caterpillar dealer, most heavy truck parts stores, NAPA (FIL 3960 crosses to 1R-0750), Amazon, and many online retailers. They're one of the most widely available filter elements in North America — and typically 30-50% cheaper than the TP3018. Q: Will this fit my 2005 LLY? A: Yes — compatible with 2005-2016 Duramax engines (LLY, LBZ, LMM, LML). If you have a 2001-2004 LB7, the filter housing mounting points are different — check fitment carefully. Q: Is the 2-micron filtration too restrictive for a tuned engine? A: No — the CAT 1R-0750 filter has a larger pleated surface area than the TP3018, so despite the tighter micron rating, it actually provides equal or better flow. This makes it ideal for tuned/towing trucks that demand maximum fuel delivery. Many 600+ hp Duramax builds use the 1R-0750 filter setup. Q: Does this kit include a WIF sensor? A: The filter head includes a pre-threaded WIF sensor port. Your existing water-in-fuel sensor transfers directly from the old housing. If your sensor is failing, we recommend replacing it during the swap. Q: Can I switch back to TP3018 filters later? A: Yes — the 1R-0750 adapter is removable. Simply unbolt it from the filter head and you're back to the standard M36 x 1.5 thread for TP3018 filters. Q: Do I need to tune the ECU after installing this? A: No tuning required. The filter head and adapter are purely mechanical components — they don't change fuel pressure, timing, or any ECM-managed parameters. It's a bolt-on hardware upgrade only. Q: What's included in the 12642623 + 1R-0750 kit vs. just the filter head?A: This kit includes two components: (1) The 12642623 billet aluminum filter head with integrated hand primer pump and fuel heater — replaces your factory plastic housing, and (2) The 1R-0750 Refit Adapter — a CNC-machined black anodized aluminum adapter that bolts to the filter head and converts the thread pattern to accept CAT 1R-0750 spin-on filters. If you only need the filter head (standard TP3018 thread), you can purchase the housing separately. The 1R-0750 adapter adds 2-micron absolute filtration capability and lets you use CAT filters available at any heavy equipment dealer nationwide. Q: Why convert to CAT 1R-0750 filters?A: The CAT 1R-0750 is widely considered the gold standard in spin-on diesel fuel filtration: 2-micron absolute rating (vs. 4-micron for standard TP3018), advanced AquaBlock water separation media, higher flow capacity for tuned/towing trucks, and nationwide availability at any Caterpillar dealer or truck stop. The conversion has been a popular Duramax modification for over 15 years — it's the same filter used on million-mile CAT heavy equipment engines. Once converted, replacement filters are widely available and the tighter filtration provides an extra margin of safety for your CP3 injection pump and fuel injectors. 📖 Related Guides Duramax Fuel Filter Housing: Complete Compatibility & Replacement Guide (2001–2024) 🔧 Complete Your Fuel System Fuel Filter Housing Assembly — related Duramax fuel system component TP3018 Fuel Filter — related Duramax fuel system component Billet Air Bleeder Screw — related Duramax fuel system component 📖 Related Guide: Duramax CAT Oil Filter Adapter Guide: 7791 Conversion — Read our in-depth maintenance guide for step-by-step instructions.

Product Overview Protect your Duramax engine's fuel injection system with the iFJF 1R-0750 Fuel Filter and Billet Aluminum Refit Head Kit. Designed as a direct replacement for the factory plastic filter housing on 2001-2016 Chevrolet Silverado and GMC Sierra 2500HD/3500HD trucks equipped with the 6.6L Duramax V8 diesel (LB7, LLY, LBZ, LMM, LML). The OEM plastic housing is notorious for cracking, leaking, and air intrusion — this billet aluminum upgrade permanently solves those issues while delivering superior filtration. The included 1R-0750 filter element features high-efficiency cellulose/synthetic media rated at 2-micron absolute filtration, capturing 99.9% of harmful contaminants before they reach your injectors. With today's ultra-high-pressure common rail systems, even microscopic particles can cause catastrophic injector failure. This kit provides OEM-spec or better protection at a fraction of dealer pricing. Key Features Billet 6061-T6 Aluminum Construction: CNC-machined from solid billet — far stronger than factory plastic. Resists heat cycling, vibration, and chemical degradation. Direct Bolt-On Installation: Uses factory mounting points and fuel line connections. No drilling, cutting, or modifications required. 2-Micron Absolute Filtration: 1R-0750 filter element provides excellent water separation and particulate removal. Black Anodized Finish: Corrosion-resistant coating for long-term durability in all weather conditions. Complete Kit: Includes filter head, 1R-0750 filter element, mounting hardware, O-rings, and installation guide. Lifetime Housing Warranty: The billet head is warrantied for life against manufacturing defects. Compatibility Year Make Model Engine 2001-2016 Chevrolet Silverado 2500HD/3500HD 6.6L Duramax V8 (LB7/LLY/LBZ/LMM/LML) 2001-2016 GMC Sierra 2500HD/3500HD 6.6L Duramax V8 (LB7/LLY/LBZ/LMM/LML) 2001-2007 Chevrolet Silverado 1500HD/2500 (Classic) 6.6L Duramax V8 2001-2007 GMC Sierra 1500HD/2500 (Classic) 6.6L Duramax V8 Why Upgrade from Plastic? The factory Duramax fuel filter housing (ACDelco TP3018 / GM 12642623) is made of plastic that becomes brittle over time. Common failures include: Bleeder screw threads stripping — leading to vacuum leaks and hard starts Housing body cracks — causing fuel leaks and fire hazards WIF sensor port failure — false warnings or no detection O-ring seal degradation — air intrusion causing rough idle and power loss This billet aluminum replacement permanently eliminates all of these failure points. If you're on your second or third plastic housing, this is the last one you'll ever need to buy. Specifications Specification Value Filter Element 1R-0750 (Caterpillar / Donaldson style) Filtration Rating 2 Micron Absolute Housing Material Billet 6061-T6 Aluminum Finish Black Anodized Thread Size (Inlet/Outlet) 1"-14 UNF (O-Ring Boss) Water Separation Efficiency >95% Filter Change Interval 15,000 miles (severe duty: 10,000) Installation Notes Installation is straightforward and can be completed in 30-60 minutes with basic hand tools. The kit bolts directly to the factory fuel filter housing bracket on the driver's side of the engine bay. Includes detailed installation guide with torque specifications and bleeding procedure. Recommended tools: 10mm socket, 1" wrench, flathead screwdriver, fuel line disconnect tool. FAQ Q: Will this fit my 2013 Duramax LML?A: Yes. This kit fits all 2001-2016 Duramax 6.6L engines including LB7, LLY, LBZ, LMM, and LML. The filter head mounts to the factory bracket on the driver's side. Q: Is the 1R-0750 filter the same as the CAT filter?A: Yes. The 1R-0750 is a Caterpillar-spec filter that is widely used as an upgrade for Duramax fuel systems. It offers 2-micron filtration, which is far superior to the factory 7-micron element. Q: Does this kit delete the factory fuel heater?A: The factory fuel heater is integrated into the stock filter head. This refit head does not include a heater element. For cold climate operation, we recommend using a winter-blend diesel fuel additive. Q: Can I use my existing WIF sensor?A: Yes, the refit head is machined to accept the factory Water-In-Fuel sensor. Simply thread it into the provided port using the supplied O-ring. Q: How often should I change the filter?A: We recommend every 15,000 miles under normal driving conditions, or every 10,000 miles for severe duty (towing, off-road, dusty environments). Always carry a spare filter on long trips.

Cold-Start Heater Element: Integrated fuel heater element warms diesel fuel during cold starts — critical for winter operation and preventing fuel gelling. Specifications Specification Detail Part Number FJ-FORD04-ZH1 OEM Reference F2TZ-9B249-A, F2TZ-9J294-A, E8TZ-9B249-A Engine 6.9L IDI (1983-1987) / 7.3L IDI (1988-1994) Material Aluminum Housing with Heating Element Includes Housing Header, Heater Element 9J294 Fits F150 F250 F350 Super Duty E150 E250 E350 F59 Warranty 12-Month Warranty Why Choose iFJF? The factory fuel filter housing on the IDI diesel is prone to corrosion, leaking, and heater element failure — especially after 30+ years of service. A leaking housing introduces air into the fuel system, causing hard starts, rough idle, and power loss. Our iFJF replacement kit solves both the housing and heater element in one purchase at a competitive price. Frequently Asked Questions Q: Will this fit my 1991 F250 7.3L IDI?A: Yes. Direct fit for all 1988-1994 7.3L IDI and 1983-1987 6.9L IDI naturally aspirated diesel engines. Q: Does this fit the 7.3L Powerstroke (1994.5+)?A: No. This is for the IDI (Indirect Injection) diesel only — not the 7.3L Powerstroke (direct injection) introduced in mid-1994. The Powerstroke uses a completely different fuel filter system. Q: Does this include the heater element?A: Yes. This complete kit includes both the housing header (F2TZ-9B249-A) and the heater element (F2TZ-9J294-A). Q: What are signs of a failing fuel filter housing?A: Fuel leaks at the filter housing, air in fuel lines (hard starting/stalling), diesel smell under the hood, and cold-start difficulty if the heater element fails. Q: Is this for turbo or non-turbo IDI?A: This fits naturally aspirated IDI engines. For factory turbo IDI (1993-1994), verify the filter base — some turbo models used a different configuration. Q: How difficult is the installation?A: Intermediate DIY. Requires basic hand tools and fuel line wrenches. Purge the fuel system after installation by cycling the key. Budget 1-2 hours. Q: Does this include the fuel filter itself?A: No. The fuel filter element is sold separately. This kit includes the housing header and heater element — the assembly that the filter screws onto.

FD-4625 Fuel Filter Element for 2017-2019 Ford 6.7L Powerstroke — OEM-Grade Replacement The FD-4625 Fuel Filter Element is the direct OEM replacement for 2017, 2018, and 2019 Ford 6.7L Powerstroke diesel engines. This cartridge-style drop-in filter replaces Motorcraft FD-4625 (HC3Z-9N184-B & HC3Z-9N184-C) with equivalent 10-micron filtration performance at a fraction of dealer pricing. Precision-engineered for the second-generation 6.7L fuel system, this filter protects your high-pressure CP4.2 injection pump from water and particulate contamination. Second-Gen 6.7L Fuel System: What Changed in 2017 For the 2017 model year, Ford redesigned the 6.7L Powerstroke fuel filter housing from the earlier spin-on design (FD-4615) to a cartridge-style system. The FD-4625 drops into a permanent canister mounted on the driver-side frame rail, using a replaceable element instead of a disposable canister. This design improves serviceability and reduces waste — but it also means you cannot use 2011-2016 spin-on filters in a 2017+ truck. Make sure you're ordering the correct filter type. Key Features 10-Micron Filtration: Captures 99% of particles at 10 microns, matching OEM HC3Z-9N184-B specifications for reliable CP4.2 pump protection. Exact OEM Fit: Precision-molded end caps and O-ring grooves ensure a leak-free seal inside the factory filter housing — no modifications needed. Complete Kit: Includes filter element + replacement housing O-ring. Everything you need for a standard service. IATF 16949 Certified: Manufactured under automotive quality management standards, delivering OEM-equivalent reliability at aftermarket pricing. Extended Service Life: Rated for 22,500-mile service intervals under normal driving conditions (15,000 miles for severe duty/towing).

No 2-week AliExpress wait times. 12-Month Warranty — Every iFJF filter is backed by our hassle-free replacement guarantee. Frequently Asked Questions Q: FD-4625 vs. FD-4624 — what's the difference and which one do I need? A: FD-4624 was the original part number when the second-gen 6.7L launched in 2017. Motorcraft superseded it with FD-4625, which uses improved filtration media for better water separation and longer service life. FD-4625 is 100% backward-compatible with all 2017-2019 applications. If you're seeing FD-4624 referenced, the FD-4625 in this listing is the correct current replacement. Q: Will this fit my 2017/2018/2019 F-250 or F-350? A: Yes — the FD-4625 fits all 2017, 2018, and 2019 Ford F-250, F-350, F-450, and F-550 Super Duty trucks with the 6.7L Powerstroke V8 diesel engine. It does NOT fit 2011-2016 models (they use spin-on FD-4615) or 2020+ models (they use FD-4631). Always confirm your model year before ordering. Q: How often should I replace the fuel filter on my 6.7L Powerstroke? A: Ford recommends every 22,500 miles (typically every 3rd oil change at 7,500-mile intervals). If you tow heavy, idle frequently, run biodiesel blends above B5, or operate in dusty conditions, replace every 15,000 miles. Always drain the water separator at every oil change regardless of mileage. Q: Why is my 2017+ 6.7L hard to start after sitting overnight? A: The #1 cause is a cracked fuel return line connector (HC3Z-9A564-A) allowing air into the system and fuel to drain back to the tank. Replace this $15 plastic connector before replacing injectors or high-pressure pumps. Second most common cause: a worn housing cap O-ring letting air in — always replace the O-ring with every filter change. Q: Can I reuse the old O-ring if it looks fine? A: No. The housing cap O-ring is a one-time-use seal. Even if it looks fine, heat cycling causes micro-compression that prevents a proper seal on reinstallation. A leaking O-ring can cause extended cranking, rough idle, and eventual CP4.2 damage from air in the fuel system. Every FD-4625 kit includes a new O-ring — use it. Q: What tools do I need to change this filter? A: A 36mm socket (or 1-7/16" SAE) for the housing cap, a 6mm hex key (Allen wrench) for the drain plug, a drain pan to catch fuel, and shop rags. No special tools required. Most DIYers complete the job in 20-30 minutes.

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

Compatibility Specification Detail Vehicle Ford F-250/F-350/F-450/F-550 Super Duty Engine 6.7L Powerstroke V8 Turbo Diesel Year Range 2011-2020 Replaces Part # BF7967, 33393 Micron Rating 2-10 Micron Absolute Filter Type Spin-On with Water Separation Why Upgrade Your Fuel Filtration? Extended Injector Life: Injectors operating at 30,000+ PSI have micron-level clearances. Better filtration means injectors lasting 200K+ miles instead of failing at 100K. Improved Cold-Weather Reliability: Superior water separation prevents ice crystal formation in fuel lines during winter. Reduced Maintenance Costs: Preventing one HPFP failure saves $5,000-$10,000 — the cost of a lifetime of premium filters. Better Fuel Economy: Clean injectors atomize fuel more efficiently, maintaining optimal combustion over the vehicle lifetime. Installation Guide Safety First: Park on level ground, engage parking brake, allow engine to cool. Have a drain pan ready. Relieve Fuel Pressure: Remove fuel cap. On some models, pull fuel pump fuse and crank briefly. Remove Old Filter: Use oil filter wrench to loosen. Unscrew by hand and lower into drain pan. Prep New Filter: Apply thin film of clean diesel to gasket. Pre-fill if housing design allows. Install: Spin on by hand until gasket contacts. Tighten 3/4 to 1 full turn. DO NOT over-tighten with wrench. Prime System: Cycle key ON (not START) 5-6 times for 30 seconds each to purge air. Check for leaks. Start & Verify: Start engine, check for leaks at idle, let run 2 minutes, recheck. Dispose of old filter properly. Frequently Asked Questions Q: Will this void my Ford warranty?A: No. Under the Magnuson-Moss Warranty Act, Ford cannot void warranty for aftermarket parts unless they prove the part caused failure. This filter meets or exceeds all OEM specifications. Many dealers install these kits. Q: What is the benefit of 5-micron vs 10-micron?A: 5-micron captures particles half the size of factory 10-micron. The Bosch CP4.2 high-pressure fuel pump in the 6.7L has extremely tight internal clearances sensitive to contamination. 5-micron = 2x better injector and pump protection. Q: Is this a complete kit?A: Yes. Includes: billet aluminum filter housing (replaces plastic OEM lower), 5-micron fuel filter element, O-ring seals, and installation instructions. Uses existing mounting bracket and fuel line connections. 30-45 minute install. Q: Do I need to tune or reprogram?A: No tuning required. Mechanical bolt-on upgrade that works with stock ECM calibration. Fuel flow rates remain within factory parameters. Simply prime system by cycling key 5-6 times before starting to purge air.

iFJF TP1015 Fuel Filter — 5-Micron Absolute Protection for Your Duramax L5P Already running an upgraded billet aluminum housing cap? Excellent choice. Now keep it fed with the iFJF TP1015 replacement fuel filter element — the same 5-micron absolute-rated filter that ships in our combo kits, sold standalone for customers who already made the cap upgrade. Same filtration. Same Viton O-rings. Same CP4.2 pump protection. Just the filter, no cap included. Engineered for 2017–2020 Chevy Silverado & GMC Sierra 2500HD/3500HD with the 6.6L L5P Duramax diesel engine, the TP1015 delivers filtration performance that leaves the OEM ACDelco paper element in the dust — literally. If your current filter has 15,000+ miles on it, you're overdue. 📊 TP1015 vs. OEM ACDelco Filter Element Specification iFJF TP1015 OEM ACDelco TP1015 Micron Rating 5 Micron (Absolute) 7–10 Micron (Nominal) Filter Media Multi-Layer Synthetic Blend Cellulose Paper Water Separation 98% Efficiency ~95% Efficiency O-Ring Material 2 × Viton® (Diesel-Rated, 400°F) 1 × Standard Nitrile Dirt-Holding Capacity 2× OEM Capacity Baseline Price $17.99 $29–$42 🚛 Compatible Vehicles Chevrolet Silverado 2500HD / 3500HD 2017 · 2018 · 2019 · 2020 6.6L L5P Duramax Turbo Diesel V8 GMC Sierra 2500HD / 3500HD 2017 · 2018 · 2019 · 2020 6.6L L5P Duramax Turbo Diesel V8 Also Fits: Chevy Cruze 2.0L Diesel (2014–2015), Chevy Cruze 1.6L Diesel (2017–2019) 🔢 Cross-Reference / Replaces OEM Part Numbers iFJF: TP1015 ACDelco: TP1015 · 22937279 GM Genuine: 23456595 · 23304096 ⚙️ Technical Specifications Filter Media: Multi-layer synthetic blend with hydrophobic barrier layer — traps particles down to 5μm while repelling water droplets from the fuel stream Filtration Rating: 5 micron absolute (β≥1000) — captures 99.9% of particles ≥5μm. OEM paper filters are rated nominally at 7–10μm, meaning they let significantly more particulate through to your CP4.2 high-pressure pump Water Separation: 98% removal efficiency — the hydrophobic layer strips emulsified water from diesel fuel, critical for protecting the CP4.2 injection pump from cavitation erosion and catastrophic failure O-Rings: 2 premium Viton® fluoroelastomer O-rings (1 × large cap seal, 1 × small filter seal) — rated to 400°F continuous, compatible with ULSD, B20 biodiesel, and common diesel fuel additives Service Interval: Replace every 15,000–22,500 miles (24,000–36,000 km). Reduce to 15,000 miles if towing heavy, extended idling, or running biodiesel blends Filter Construction: Spiral-wound pleated media with epoxy-sealed end caps — no bypass valve failures, consistent flow under high fuel demand 📦 What's in the Box 1 × TP1015 Fuel Filter Element (multi-layer synthetic blend media, 5μm absolute) 2 × Viton® O-rings (large cap seal + small filter seal) 1 × Installation instruction card ⚠️ Housing cap NOT included — this is the filter element only. If you need a cap upgrade, see our Silver Cap Kit or Black Cap Kit. 🛠️ Installation Tips PRIME THE FILTER: Fill the new filter with clean diesel before installing. A dry filter means a dry CP4.2 on first start — and that can lead to a $4,000+ pump replacement. LUBE THE O-RINGS: Apply a thin film of clean diesel or silicone grease to both O-rings. Dry O-rings can pinch, tear, or roll during installation — all of which cause air leaks and hard-start conditions. TORQUE TO SPEC: If you're using the OEM plastic cap, torque to 18 ft-lbs (25 N·m) — no more. If you're using an iFJF billet aluminum cap, the same torque spec applies, but the aluminum cap won't crack if you go slightly over. BLEED THE SYSTEM: After installation, cycle the key to "ON" (without cranking) 3–5 times. You'll hear the in-tank lift pump cycle. The L5P fuel system is self-priming — no manual bleeding required. LEAK CHECK: Start the engine and inspect the filter housing area. Any dampness around the cap seal means the O-ring isn't seated. Shut down, reseat, and retorque. ❓ FAQ Q: Will this fit my 2017–2020 Duramax L5P? A: Yes — as long as your truck uses the cartridge-style fuel filter housing (GM part #134001 housing). This filter fits all 2017–2020 Silverado/Sierra 2500HD/3500HD with the 6.6L L5P engine. Also fits Chevy Cruze 1.6L/2.0L diesel models. Q: How often should I replace the fuel filter? A: GM recommends every 22,500 miles. We recommend every 15,000 miles if you tow heavy, idle frequently, or run any biodiesel blends. The TP1015 has 2× the dirt-holding capacity of the OEM filter, but diesel fuel quality varies — err on the side of more frequent changes. Q: Can I use this TP1015 filter with the OEM plastic cap? A: Yes, the TP1015 filter element is a direct dimensional match for the OEM housing. However, the factory plastic cap is a known failure point (GM TSB #18-NA-103). We strongly recommend upgrading to our 6061-T6 billet aluminum cap for permanent peace of mind. Q: Will using this aftermarket filter void my factory warranty? A: No. Under the Magnuson-Moss Warranty Act (15 U.S.C. § 2302), a manufacturer cannot void your warranty for using aftermarket parts unless they prove the aftermarket part directly caused the failure. The iFJF TP1015 meets or exceeds all OEM filtration specifications — GM would have a very hard time making that case. 🛒 Complete Your Fuel System Upgrade This filter is just one piece of the L5P fuel system puzzle: Need the billet cap?
