iFJF TP1015 Fuel Filter Kit for GM 6.6L L5P — Red Anodized Aluminum Cap, 5‑Micron Filter

iFJF TP1015 replacement fuel filter and anodized aluminum housing cap kit restores reliable fuel filtration and a stronger drain system for GM Duramax 6.6L L5P engines. This complete replacement kit includes a high-efficiency 5-micron fuel filter cartridge, a CNC-machined 6061-T6 aluminum housing cap with stainless-steel drain plug, and two O-rings for a straightforward swap on compatible GM models. Built to replace the TP1015 filter and OEM cap (134001), the kit improves water separation, resists corrosion, and avoids the cracking issues sometimes seen with stock caps when tightened. It’s designed for 2017–2024 Duramax 6.6L V8 applications (Chevy Silverado/GMC Sierra 2500HD/3500HD) and also fits certain Cruze models listed.

How does this kit improve fuel filtration compared with the stock unit?

The iFJF filter element is rated at 5 microns with a 98% water separation efficiency, which captures fine particulates and removes entrained water more effectively than many older or worn stock elements. Better filtration helps maintain injectors and fuel system components by keeping contaminant levels low.

• 5-micron filter media for fine particle capture
• 98% water separation efficiency to reduce moisture in fuel
• Full replacement element rather than a partial service option

Why choose the aluminum housing cap and stainless drain plug?

The housing cap is CNC-machined from 6061-T6 billet aluminum and anodized to resist corrosion and abrasion, giving higher mechanical durability than some OEM polymer caps that can crack if over-torqued. The included stainless-steel drain plug resists rust and delivers a long-lasting drain point for water and sediment removal.

• 6061-T6 billet construction resists cracking and deformation
• Anodized finish for abrasion and corrosion protection
• Stainless-steel drain plug provides a durable, rust-resistant drain

Will this replace my existing TP1015 filter and cap directly?

Yes—the kit is made to directly replace the TP1015 filter cartridge and the 134001 housing cap, and supports listed part numbers like 22937279 and 23456595 for cross-compatibility. It ships with two O-rings so you have the sealing parts required for a correct installation.

• Direct replacement for TP1015 and cap 134001
• Compatible with cross-reference numbers included in product specs
• Includes two O-rings for proper sealing at installation

How should I maintain this filter to keep fuel performance steady?

Regular inspection and scheduled replacement according to your vehicle’s maintenance intervals will keep fuel flow and filtration at peak performance. When you drain water or sediment using the stainless plug, inspect the drain contents and replace the cartridge if contamination is present or after the recommended service interval.

• Check filter at manufacturer-recommended intervals or if performance changes
• Use the stainless drain to remove collected water/sediment periodically
• Replace the cartridge and O-rings during service to ensure a tight seal

This kit is tailored for owners and technicians who want a durable, performance-focused replacement for their Duramax fuel system—especially those who experience cracked OEM caps, routine water in the fuel, or who prefer a metal housing with a stainless drain for longevity. It’s a practical upgrade for fleet maintenance, owner-operators, and DIY mechanics who need all necessary parts in one package: housing cap, durable drain plug, filter cartridge, and O-rings. Follow vehicle-specific procedures and torque specs during installation to ensure correct fit and leak-free operation.
