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. LUBE THE O-RINGS: Apply a thin film of clean diesel or silicone grease to both O-rings before installation. TORQUE TO SPEC: Hand-tighten, then torque to 18 ft-lbs (25 N·m). Threads engage smoothly — if you feel 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: 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.
