DESCRIPTION
Product Overview
- Protect your high-pressure common-rail diesel injection system from costly contamination and moisture damage with this premium replacement diesel fuel filter cartridge. Engineered with an advanced multi-layer coalescing media stack, it delivers an outstanding 98%+ water separation efficiency, stripping away microscopic water droplets, rust, and particulate matter before they can reach sensitive injectors and fuel pumps.
- Designed for an exact OEM drop-in fit, this filter cartridge maintains consistent fuel pressure and unrestricted flow under heavy towing and demanding workloads. The fatigue-resistant housing and included premium sealing O-rings form a leak-free seal within the fuel filter assembly, ensuring clean, dry diesel fuel delivery for optimal engine efficiency and long-term durability.
Key Features
- Advanced multi-layer coalescing media mechanically separates emulsified water and traps microscopic dirt to protect high-pressure common-rail injectors and fuel pumps.
- High-strength, cycle-tested composite end caps resist thermal expansion and stress fractures under extreme cold and hot operating cycles.
- Precision-engineered seal grooves and included high-grade O-rings establish a leak-free seat, preventing fuel pressure loss and air intrusion.
- High-capacity pleated media structure maintains smooth diesel fuel flow while providing deep contaminant loading endurance for heavy-duty towing.
Replacement Interval
-
Replace the diesel fuel filter every 15,000 to 20,000 miles under normal driving conditions. For trucks frequently subjected to heavy towing, biodiesel blends, or regions with inconsistent fuel quality, reduce the service interval to 10,000 to 15,000 miles.
FAQ
Q: Can I use the older TP3018 spin-on fuel filter on my newer Duramax truck?
A: No. Newer platforms transitioned to a cartridge-style fuel filter design housed within a dedicated filter bowl. The older TP3018 spin-on filter is physically incompatible. You must use the TP1015 cartridge element.
Q: Do I need any special tools to replace this fuel filter cartridge?
A: No specialized filter wrenches are required. You only need a standard socket wrench to unscrew the bottom filter housing cap. The old cartridge then lifts out by hand, and the new filter drops directly into place.
Q: Should I replace the included rubber O-rings every time I change the fuel filter?
A: Yes, always. Replacing the housing cap O-rings with the fresh ones provided in the package ensures a proper airtight and leak-free seal. We recommend applying a light coating of clean diesel fuel or clean engine oil to the new O-rings before torquing the cap down.
Q: Should I drain the water separator before or after changing the filter?
A: You should always open the drain valve and drain the water separator first before removing the filter housing cap. Draining the housing prevents water and trapped contaminants from spilling or entering the clean side of the fuel system during the swap.
Q: Is there a complete maintenance package available to service all filters at once?
A: The 2020-2026 Fuel & Oil Combo pairs this fuel filter with the matching PF26 oil filter. For full 4-filter coverage, step up to Full Maintenance Kit.
