Upgrade Your Duramax L5P Fuel System — TP1015 Filter & 6061-T6 Billet Aluminum Housing Cap Engineered for 2017–2020 Chevy Silverado & GMC Sierra 2500HD/3500HD equipped with the 6.6L L5P Duramax diesel engine, the iFJF TP1015 Fuel Filter & 134001 Housing Cap Combo Kit solves the two biggest pain points of L5P fuel system maintenance: factory plastic cap failures and subpar filtration. One kit. One install. Total peace of mind. 🔧 The Problem with OEM L5P Fuel Filter Caps The factory 134001 plastic housing cap on 2017–2020 Duramax L5P trucks is a known weak point. Overtighten it by even a quarter turn and the plastic cracks — leaving you with a fuel leak, a check engine light, and a $200+ tow to the nearest shop. GM TSB #18-NA-103 documents this exact issue. iFJF replaces that brittle plastic with a CNC-machined 6061-T6 billet aluminum cap — the same aerospace-grade alloy used in performance fuel systems. It won't crack. It won't warp. It won't leave you stranded. 📊 Why iFJF TP1015 vs. OEM Specification iFJF TP1015 OEM (ACDelco) Cap Material 6061-T6 Billet Aluminum Nylon Plastic Filter Micron Rating 5 Micron (Absolute) 7–10 Micron (Nominal) Water Separation 98% Efficiency ~95% Efficiency Filter Media Multi-Layer Synthetic Blend Cellulose Paper O-Ring Included ✅ 2 Premium Viton O-Rings ✅ 1 Standard O-Ring Drain Plug Anodized Aluminum (5 Color Options) Plastic (Non-Serviceable) Price (Filter + Cap) $69.99 $95–$130 (Filter + Cap separately) 🚛 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 Fuel Filter: TP1015 · 22937279 · 23456595 · 23304096 · ACDelco TP1015 Housing Cap: 134001 · ACDelco 134001 ⚙️ Technical Specifications Filter Media: Multi-layer synthetic blend with pleated cellulose core — superior dirt-holding capacity vs. OEM paper Filtration Rating: 5 micron absolute — captures 99.9% of particles ≥5μm (OEM paper elements typically rate 7–10μm nominal) Water Separation: Hydrophobic barrier layer achieves 98% water removal efficiency, protecting CP4.2 high-pressure fuel pump from water-induced cavitation damage Cap Material: CNC billet 6061-T6 aluminum with black anodized finish on Silver variant Cap Design: 32mm hex head for standard socket wrench — no special tools needed Drain Plug: Integrated anodized aluminum drain valve for easy water drainage during service intervals O-Rings: 2 premium Viton® fluoroelastomer O-rings (cap seal + filter seal) — rated to 400°F, diesel-resistant Service Interval: Replace every 15,000–22,500 miles (24,000–36,000 km) or per GM maintenance schedule Torque Spec: 25 ± 3 N·m (18 ± 2 ft-lbs) — no risk of cracking vs. plastic cap 🎨 Available Finishes — 5 Anodized Colors Choose the cap color that matches your build: 🔴 Red — Aggressive, race-inspired look 🟡 Gold — Premium, standout finish 🟢 Green — Subtle OEM+ appearance ⚪ Silver — Classic machined aluminum with black trim ⚫ Black — Stealth, factory-look finish 📦 What's in the Box 1 × TP1015 Fuel Filter (multi-layer synthetic blend media, 5μm) 1 × 134001 Housing Cap (CNC 6061-T6 billet aluminum) 1 × Anodized aluminum drain plug (pre-installed) 2 × Viton® O-rings (large cap seal + small filter seal) 1 × Installation instruction card 🛠️ Installation Tips PRIME THE FILTER: Fill the new filter with clean diesel before installing — this prevents the CP4.2 pump from running dry on first start.

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: Will this fit my 2021+ L5P Duramax? A: No. GM changed the fuel filter housing design for 2021+ model years. This kit is specifically for 2017–2020 L5P trucks. For 2021+, use our updated L5P 2021+ filter kit. Q: How often should I replace the fuel filter? A: GM recommends every 22,500 miles under normal conditions. If you tow heavy, idle frequently, or run biodiesel blends, replace every 15,000 miles. Q: Can I reuse the aluminum cap with future filter changes? A: Yes! The 6061-T6 cap is a lifetime upgrade. Only the filter element and O-rings need replacement at each service interval. We sell replacement filter-only kits. Q: Does this void my warranty? A: No. Under the Magnuson-Moss Warranty Act, using aftermarket parts does not automatically void your warranty. The TP1015 meets or exceeds all OEM filtration specs. ⚠️ IMPORTANT: Always prime the fuel filter with clean diesel before installation. A dry-start CP4.2 high-pressure pump can cause catastrophic failure — a $4,000+ repair you don't want. 🔗 L5P Duramax Resources 📖 Installation Guide: L5P Fuel Filter Housing Cap Replacement — Complete DIY Guide (2017–2020) — step-by-step, torque specs, CP4.2 protection. 🛒 134001 Billet Aluminum Fuel Filter Housing Cap (Silver) — CNC 6061-T6, lifetime upgrade, standalone cap 🛒 TP1015 Replacement Fuel Filter Element — 5-micron absolute, 98% water separation, $19.99 🛒 A3231C Air Filter for L5P Duramax — high-flow replacement for 2017–2019 Silverado/Sierra 2500HD 3500HD 🛒 TP1015 Fuel Filter + A3231C Air Filter Combo — save on both filters for your L5P 🔍 Shop All Duramax 6.6L Parts → 🔍 Browse All Fuel Filters → Related Guide Read: Duramax 6.6L L5P Fuel Filter Replacement: Complete Step-by-Step Guide 🔩 Upgrade to the billet 134001 housing cap — the cap included in this combo

Fuel Filter Assembly for 1992-2002 Chevy GMC 6.5L Diesel — Suburban, Silverado, Sierra, Tahoe, Yukon, Hummer H1 Looking for a fuel filter for your Chevy Suburban 6.5 diesel? Or maybe a GMC Sierra 2500 6.5 diesel fuel filter? This assembly fits them all. Whether you drive a 1994 K2500 work truck, a 1998 Suburban family hauler, a 1995 Tahoe, or a Hummer H1, this complete fuel filter assembly replaces your worn-out filter housing, heater, and filter element in one bolt-on job. OEM part number: 10226035. If your current filter housing is cracked, leaking fuel, has a failed heater connector, or the water-in-fuel sensor is malfunctioning — replacing the entire assembly is more reliable (and often cheaper in labor) than piecing together individual components. This kit includes the filter head, metal housing with integrated fuel heater, mounting bracket, water sensor port, and a fresh filter element — all pre-assembled and ready to bolt on. Why Replace the Whole Assembly? The GM 6.5L diesel's fuel filter housing is a known failure point on high-mileage trucks. The plastic OEM housings warp over time from engine heat, causing air intrusion and hard-starting issues. The fuel heater element can short out, and the threaded fittings can strip. A complete assembly swap solves all these problems at once — and this aftermarket unit uses a metal housing that outlasts the factory plastic design. ⓘ Fitment Note: This assembly fits 1992-2002 GM trucks and SUVs with the 6.5L V8 diesel (engine codes L49/L56/L57/L65). It also fits some 5.7L and 7.4L diesel/gas applications that used this filter style. Not compatible with 2001+ Duramax 6.6L (LB7/LLY/LBZ/LMM/LML/L5P) — those use a completely different filter system. Key Features All-in-One Kit — Filter head, metal housing, fuel heater with connector, water-in-fuel sensor port, mounting bracket, O-rings, and filter element — everything pre-assembled Metal Housing Construction — Far more durable than OEM plastic under sustained engine bay heat and vibration Integrated Fuel Heater — Prevents fuel gelling in cold weather; essential for winter operation in northern climates Water-in-Fuel Sensor Port — Retains factory WIF sensor functionality; compatible with original wiring connector 30-Micron Filtration Media — Cellulose/synthetic blend filter element traps contaminants before they reach the injection pump and injectors Pre-Threaded Mounting Points — Direct bolt-on — no drilling, tapping, or modifications needed Reusable Housing — When it's time for a filter change, just swap the TP1256 replacement element — no need to replace the entire assembly Complete Vehicle Compatibility Chevrolet Model Years Engine Notes Blazer (Full-Size K5) 1992–1999 6.5L V8 Diesel K5 Blazer / Tahoe predecessor C1500 / Silverado 1500 1992–1999 6.5L V8 Diesel 2WD 1/2-ton pickup C1500 Suburban 1992–1999 6.5L V8 Diesel 2WD 1/2-ton SUV C2500 / Silverado 2500 1992–2000 6.5L V8 Diesel 2WD 3/4-ton pickup C2500 Suburban 1992–1999 6.5L V8 Diesel 2WD 3/4-ton SUV C3500 / Silverado 3500 1992–2002 6.5L V8 Diesel 2WD 1-ton pickup C3500HD 1992–2002 6.5L V8 Diesel 2WD heavy-duty chassis cab Express 1500/2500/3500 1996–2002 6.5L V8 Diesel Full-size van G20 / G30 1992–1996 6.5L V8 Diesel Predecessor to Express van K1500 / Silverado 1500 4WD 1992–1999 6.5L V8 Diesel 4WD 1/2-ton pickup K1500 Suburban 1992–1999 6.5L V8 Diesel 4WD 1/2-ton SUV K2500 / Silverado 2500 4WD 1992–2000 6.5L V8 Diesel 4WD 3/4-ton pickup K2500 Suburban 1992–1999 6.5L V8 Diesel 4WD 3/4-ton SUV K3500 / Silverado 3500 4WD 1992–2002 6.5L V8 Diesel 4WD 1-ton pickup P30 1992–1999 6.5L V8 Diesel Forward-control chassis (step van/motorhome) Tahoe (2-door & 4-door) 1995–1999 6.5L V8 Diesel Full-size SUV GMC Model Years Engine Notes C1500 / Sierra 1500 1992–1999 6.5L V8 Diesel 2WD 1/2-ton pickup C1500 Suburban 1992–1999 6.5L V8 Diesel 2WD 1/2-ton SUV C2500 / Sierra 2500 1992–2000 6.5L V8 Diesel 2WD 3/4-ton pickup C2500 Suburban 1992–1999 6.5L V8 Diesel 2WD 3/4-ton SUV C3500 / Sierra 3500 1992–2002 6.5L V8 Diesel 2WD 1-ton pickup C3500HD 1992–2002 6.5L V8 Diesel Heavy-duty chassis cab G2500 / G3500 1992–1996 6.5L V8 Diesel Full-size van K1500 / Sierra 1500 4WD 1992–1999 6.5L V8 Diesel 4WD 1/2-ton pickup K1500 Suburban 1992–1999 6.5L V8 Diesel 4WD 1/2-ton SUV K2500 / Sierra 2500 4WD 1992–2000 6.5L V8 Diesel 4WD 3/4-ton pickup K2500 Suburban 1992–1999 6.5L V8 Diesel 4WD 3/4-ton SUV K3500 / Sierra 3500 4WD 1992–2002 6.5L V8 Diesel 4WD 1-ton pickup P3500 1992–1999 6.5L V8 Diesel Forward-control chassis Savana 1500/2500/3500 1996–2002 6.5L V8 Diesel Full-size van Yukon (2-door & 4-door) 1992–1999 6.5L V8 Diesel Full-size SUV AM General Model Years Engine Hummer H1 1994–2001 6.5L V8 Turbo Diesel Cross-Reference Part Numbers GM OEM: 10226035, 10154635, 10183997, 25176756 Aftermarket: TP1256, BF1201, P550352, FS1295, PS7358 ACDelco: TP1256, 33376, 33976 WIX: 33379 NAPA: 3960 Other: 5742602, XF54719, F54719 Technical Specifications Specification Detail Filtration Rating 30 Micron (nominal) Filter Media Cellulose / synthetic blend Housing Material Metal (steel) with corrosion-resistant coating Fuel Heater Integrated 12V heating element with OEM-style connector WIF Sensor Port Compatible with factory water-in-fuel sensor Inlet/Outlet Size 3/8\" quick-connect (matches OEM) Filter Replacement Interval Every 10,000-15,000 miles Weight Approx. 2.6 lbs (1.17 kg) Installation Overview Relieve fuel system pressure and disconnect battery Disconnect fuel lines (quick-connect fittings) and WIF sensor connector Remove mounting bolts from old filter housing bracket Install new assembly — bolts directly to factory mounting points Reconnect fuel lines, WIF sensor, and heater connector Prime fuel system by cycling ignition key (ON for 10 seconds, OFF, repeat 3-4 times) Start engine and check for leaks at all connections ⚠️ Torque Warning: When tightening the filter cap onto the housing, hand-tighten firmly then add no more than 1/4 turn with a wrench. Over-tightening is the #1 cause of cap leaks and difficult future filter changes. The O-ring does the sealing — not raw torque. FAQ Q: Will this fit my 1994 Chevy K2500 with the 6.5L turbo diesel?A: Yes. This assembly directly fits all 1992-2002 GM C/K 1500, 2500, and 3500 series trucks with the 6.5L V8 diesel engine, including your 1994 K2500. Q: Does this include the filter element?A: Yes. The assembly comes with a filter element pre-installed. When it's time for your next filter change, you can purchase our replacement filter element (sold individually or in value packs of 3-pack and 6-pack). Q: My truck has a hard start and loses prime overnight. Will this fix it?A: Very likely yes. Air intrusion through a cracked filter housing or failed O-rings is one of the most common causes of hard starting and prime loss on the GM 6.5L diesel. Replacing the complete assembly with new seals and housing eliminates these leak paths. Also check your lift pump and fuel lines if the problem persists. Q: Is the fuel heater functional?A: Yes. The integrated 12V fuel heater uses the OEM-style connector and activates automatically in cold temperatures to prevent fuel gelling and improve cold-start performance. It's essential if you operate in winter conditions. Q: How does this compare to the OEM plastic housing?A: The original GM housing (ACDelco 10226035) is plastic and known to warp, crack, and leak over time — especially on high-mileage trucks. This aftermarket replacement uses a metal housing that's significantly more durable under sustained engine bay heat. It meets or exceeds OEM filtration specifications at a fraction of the dealer price. Q: Do I need to bleed the fuel system after installation?A: Yes. After installation, cycle the ignition key to the ON position (not START) for 10 seconds, then OFF for 5 seconds. Repeat 3-4 times. This runs the lift pump and purges air from the system. You should hear the pump pitch change when air is purged. Then start the engine and let it idle for 2-3 minutes while checking for leaks. Q: Will this fit my 2003 Duramax?A: No. This assembly is for the 6.5L diesel (1992-2002). Duramax 6.6L engines (2001+) use an entirely different filter system. Please check our Fuel Filter collection for Duramax-compatible options. Q: What's the difference between the filter element and the full assembly?A: TP1256 is the filter element (the replaceable cartridge with cap and gasket). 10226035 is the complete assembly — housing, heater, bracket, and filter element together. This product is the complete assembly. If you only need replacement filter elements, see our TP1256 filter element multipacks. 📦 Need Replacement Filters?

For 6.5L Diesel applications, we recommend replacing the fuel filter every 15,000-25,000 miles under normal driving conditions, or every 10,000-15,000 miles for severe service (towing, dusty environments, extended idling). Always replace both primary and secondary filters as a set. Q: What are the symptoms of a clogged fuel filter? Common signs include: hard starting or no-start condition, engine misfire or hesitation under load, reduced fuel economy, check engine light (often P0087 low fuel pressure code), rough idle, and loss of power at highway speeds. Q: Is this filter a direct OEM replacement? Yes. The fuel fuel filter is manufactured to meet or exceed OEM specifications for fit, form, and function. It drops directly into the factory filter housing with no modifications required. Q: Does this filter remove water from diesel fuel? Yes. This fuel water separator filter features a hydrophobic barrier media that effectively strips emulsified water from diesel fuel. Removing water is critical for preventing injector corrosion and microbial growth in modern high-pressure common rail fuel systems. Q: How do I know when to change my fuel filter? Monitor for performance symptoms (hard starts, power loss), follow your manufacturer's recommended service interval, and consider fuel quality — poor-quality diesel or biodiesel blends may require more frequent filter changes.

496 Fuel Filter Assembly — Complete Fuel Filtration, Right Out of the Box The iFJF 496 fuel filter assembly is a ready-to-install fuel polishing station for your tank, transfer pump, or dispensing system. It combines a 30-micron filter element, clear hyaline water-separation bowl, and zinc-plated 1" NPT top cap into one complete unit. Designed for gasoline, diesel, biodiesel (up to B20), and fuel oil — it handles up to 25 gallons per minute at 150 PSI. If your current setup has a rusty cap, a cracked bowl, or a clogged filter you can't see through, this is the drop-in upgrade. Key Features Complete Assembly — No Parts to Hunt: Comes fully assembled with the zinc 1" NPT top cap, 30-micron filter element, hyaline see-through bowl, drain valve, and gaskets — everything you need in one box. Unscrew the old unit, thread this one on, and you're filtering. 30-Micron Filtration: Traps rust, sand, dirt, pipe scale, and other particulate down to 30 microns — protecting injectors, carburetors, and fuel pumps from abrasive wear. Ideal as a primary/bulk filter before finer secondary filtration. Water Separation: The hyaline bowl acts as a gravity water separator. Water (heavier than fuel) settles to the bottom while clean fuel rises to the outlet. The clear bowl lets you see exactly when it's time to drain. High Flow — 25 GPM Max: With a 1" NPT inlet/outlet and low-restriction element, this assembly supports flow rates up to 25 gallons per minute. Perfect for fuel transfer pumps, tank filling stations, and high-volume dispensing. Zinc-Plated 1" NPT Cap: The top cap is cast and machined with 1" NPT female threads. Rust-resistant zinc plating prevents the seized-thread nightmare common with bare steel caps. Large wrench flats for easy installation. Multi-Fuel Compatible: Rated for unleaded gasoline, diesel #1/#2, biodiesel up to B20, fuel oil, and related additives. One assembly covers everything on the farm or in the shop. 150 PSI Working Pressure: Built with a substantial safety margin for typical fuel system pressures (most transfer pumps run 30-60 PSI). The thick-wall hyaline bowl and reinforced cap can handle pressure spikes without failure. What's Included Component Material Spec Top Cap Zinc-Plated Steel 1" NPT Female Inlet/Outlet Filter Element Cellulose/Synthetic Blend 30 Micron, 496-5 Compatible Filter Bowl Hyaline Polymer See-Through, Alcohol-Resistant, Drain Valve Gaskets Nitrile Rubber Bowl-to-Cap Seal (Pre-Installed) Drain Valve Brass/Bronze Bottom-Mounted, Finger-Operated Specifications Specification Value Part Number 496 / 496-ZH Filter Rating 30 Micron (Nominal) Max Flow Rate 25 GPM (95 LPM) Max Working Pressure 150 PSI Inlet / Outlet 1" NPT Female Bowl Material Hyaline Polymer (See-Through) Cap Material Zinc-Plated Cast Steel Fuel Types Gasoline, Diesel, Biodiesel (B20), Fuel Oil Replacement Element 496-5 Filter Element Typical Applications Fuel Transfer Tanks: Mount inline between your transfer tank and pump to catch tank-bottom debris before it reaches your equipment. Farm Fueling Stations: Filter bulk diesel or gasoline before it goes into tractors, combines, and trucks. The 25 GPM flow rate won't slow down your fill-ups. Above-Ground Storage Tanks: Install on the discharge side to polish fuel before dispensing. The clear bowl gives you instant visual confirmation of fuel quality. Generator Fuel Systems: Protect standby generator injectors from tank condensation and rust. The water separator is especially valuable for diesel generators that sit for months between runs. Marine Fuel Systems: Filter tank fuel before it hits your engine's primary filter. Water separation is critical in marine environments where condensation is constant. Maintenance & Replacement Filter Element: Replace every 500-1,000 gallons of fuel throughput, or when you notice reduced flow. Use the 496-5 replacement element. Bowl Inspection: Check the hyaline bowl monthly for clouding, cracking, or drain valve leakage. Replace with the 495-4 replacement bowl if needed. Water Drain: Drain accumulated water weekly (or daily in high-humidity environments). Simply crack the bottom valve until clean fuel appears. Bowl Wrench: Use the 491 bowl wrench for damage-free bowl removal — never use a strap wrench or channel locks. Frequently Asked Questions Q: What does "30 micron" mean and is it enough for my diesel engine?A: 30 micron means the filter catches particles 30 microns (0.03mm) and larger. This is the standard rating for primary/bulk fuel filtration — it stops rust, sand, and pipe scale. For final engine protection, your vehicle's onboard fuel filter (typically 2-10 micron) handles the fine stuff. The 496 assembly is designed as the first line of defense. Q: Will this work with a standard fuel transfer pump?A: Yes — it supports up to 25 GPM and 150 PSI. Most transfer pumps run at 10-20 GPM and 30-60 PSI, well within the 496's capability. The 1" NPT ports fit standard fuel plumbing. Q: Can I mount this in any orientation?A: The bowl must be oriented downward (vertical) for proper water separation. Water sinks to the bottom of the bowl — if the assembly is mounted sideways, water won't collect in the drain zone. Q: How do I know when to change the filter element?A: Three signs: (1) Reduced flow rate at the nozzle — the most obvious indicator. (2) The element looks dark and loaded when viewed through the clear bowl. (3) You've processed 500-1,000 gallons since the last change. Keep a spare 496-5 element on hand. Q: Is the 1" NPT cap compatible with my existing plumbing?A: 1" NPT is the standard size for fuel transfer and dispensing systems. Your existing fittings, nipples, or hoses should thread right in. Use PTFE thread sealant (not tape) on NPT threads for a fuel-tight seal. 📖 Related Guide: Read our complete installation guide and comparison →
