Technical Specifications Brand iFJF SKU FJ-UF-10K-LX Filter Type Fuel Filter / Water Separator Filtration Rating 10 Micron Application Marine, Yacht, Gasoline Engine Material Corrosion-Resistant Coated Steel Warranty 12-Month Limited Installation Guide Remove old filter by unscrewing counterclockwise. Apply thin film of clean fuel to new filter's gasket. Spin on clockwise until gasket contacts, then tighten additional 3/4 turn by hand. Prime fuel system and check for leaks before starting engine. Pro tip: Pre-fill the new filter with clean fuel to reduce cranking time. Frequently Asked Questions Q: How often should I replace the fuel filter water separator? Replace every 100 operating hours or annually, whichever comes first. In high-humidity or older tank environments, quarterly replacement is recommended. Q: Will this fit my outboard motor? The UF-10K uses standard spin-on mounting compatible with most marine filter heads. Verify your existing filter's thread size and gasket diameter for fitment confirmation.

Marine Fuel Filters & Water Separators

Water in fuel is the #1 enemy of marine engines. Unlike your truck, a boat fuel tank collects condensation constantly — and a single tank of water-contaminated fuel can destroy injectors, seize pumps, and leave you adrift. iFJF Direct carries marine-grade fuel water separators trusted by commercial fishermen and recreational boaters alike.

Marine Filter Lineup

  • R12T Complete Assembly: Aluminum spin-on fuel water separator with clear collection bowl. 10-micron filtration, 30 GPH flow rate. Replaces Racor S3240, Sierra 18-7987.
  • R12H Elements: Replacement 10-micron filter cartridges (1-pack and 2-pack). Spin-on design for tool-free changes.
  • S3213 Filters: 3/8" NPT port marine filters for outboard motors. Replaces 35-60494-1, 18-7932-1.

FAQ

Q: How often should I change my boat's fuel water separator?
A: Every 100 hours or annually, whichever comes first. If you fuel at marinas with questionable fuel quality or store your boat with partially full tanks, change more frequently. Always carry a spare filter element — changing a filter at sea beats getting towed.

Duramax Maintenance FAQ

How often should I change the fuel filter on a 6.6L Duramax?

GM recommends replacing the Duramax fuel filter every 15,000 to 22,500 miles, or every 12 months. If operating under heavy towing conditions or using biodiesel blends, changing it every 10,000 miles is recommended to protect the high-pressure fuel pump (CP4/HPCR). The L5P models (2017+) use a dual-filter system — both filters should be changed simultaneously for optimal protection.

Are iFJF Duramax filters compatible with OEM housings?

Yes. All iFJF Duramax oil, fuel, and CCV filters are built to exact OEM dimensions. They feature high-grade synthetic filtration media (5-micron rating on fuel filters) to ensure 98%+ water separation efficiency and zero modifications required during installation. Compatible with ACDelco, Racor, and GM factory filter housings.

What causes the "Water in Fuel" warning on my Duramax?

The "Water in Fuel" warning light indicates water accumulation in the fuel filter housing separator. This is common on LML and L5P engines. Drain the water separator immediately using the bleed screw, and consider replacing the filter if the warning persists. Upgrading to an iFJF CNC billet aluminum bleeder screw (replacing the fragile OE plastic screw) prevents stripping and ensures reliable drainage.

Do I need to prime the fuel system after changing a Duramax fuel filter?

For L5P (2017+) models with the electric lift pump, the system self-primes after filter replacement — simply cycle the key to "ON" (without starting) for 30 seconds, repeat 2-3 times. For LB7-LML models, use the manual primer pump on the filter housing until firm resistance is felt. Running the engine without proper priming can cause air in the HPCR system and potential injector damage.

What is the difference between TP1015 and TP3018 Duramax fuel filters?

TP1015 is the spin-on fuel filter used on 2017+ L5P Duramax engines (driver-side frame rail mount). TP3018 is the fuel/water separator filter for 2001-2016 LB7 through LML engines. They are not interchangeable — verify your model year before ordering. iFJF offers both types, including complete kits with upgraded CNC aluminum housing caps.

How do I know if my Duramax fuel filter housing cap needs replacement?

Common signs include: fuel seepage around the cap, difficulty achieving a proper seal after filter changes, cracked or stripped threads on the OE plastic cap, and recurring "Water in Fuel" warnings despite draining. iFJF upgraded CNC 6061-T6 billet aluminum caps (available in multiple colors for the L5P 134001 housing) permanently solve these issues with a precision-machined fit and O-ring sealing surface that outlasts the factory plastic components.
