DESCRIPTION
Product Overview
- The TruckTok Dual Fuel Filter Kit provides a comprehensive two-stage filtration shield to protect high-pressure common-rail diesel injection systems. This convenient, all-in-one package bundles both required fuel filters into a single order, simplifying your maintenance routine and keeping your engine running with peak fuel purity.
- The frame-mounted primary filter uses multi-stage media to perform the heavy lifting, stripping moisture and trapping coarse tank-sourced debris before it flows forward; its base is engineered with precision threads to seamlessly accept your factory reusable water-in-fuel (WIF) sensor. Downstream in the engine bay, the secondary cartridge filter performs high-efficiency fuel polishing to trap fine sub-micron particles, ensuring clean fuel delivery and preventing catastrophic injector wear.
Key Features
- Engineered with advanced multi-stage media featuring 5µm/3µm micron ratings to provide progressive fuel polishing from the tank to the high-pressure common-rail injectors.
- The frame-rail mounted spin-on filter performs the critical first stage of defense, stripping moisture and trapping coarse contaminants at the fuel source.
- Placed downstream in the engine bay to provide the final, high-efficiency filtration stage, capturing sub-micron particles before fuel enters sensitive injection components.
- The base of the primary chassis filter features precision-cut threads designed to seamlessly accept your reusable factory water-in-fuel (WIF) sensor and drain bowl.
Replacement Interval
-
For maximum fuel system protection, replace both fuel filters every 15,000 miles (or 12 months). Additionally, make it a routine to drain the chassis fuel-water separator at every oil change to remove accumulated moisture and prevent water from migrating toward your high-pressure injectors.
FAQ
Q: Why does the 6.7L Cummins use two fuel filters in different locations?
A: It uses a true dual-stage system: the chassis filter acts as the primary stage to strip water and coarse debris, while the engine-bay cartridge acts as the secondary stage to polish out fine sub-micron particles. Replacing both ensures maximum protection for your sensitive common-rail injectors.
Q: What happens if I only replace one of the two fuel filters?
A: It compromises the entire system. A dirty secondary filter restricts fuel flow to the pump, while a clogged primary filter forces unfiltered fuel into the new secondary, plugging it prematurely. Always replace both together every 15,000 miles.
Q: How do I prime the fuel system after replacing both filters?
A: Do not crank the engine immediately. Close all drains, cycle your key to the "ON" position (engine off) for 30 seconds, then "OFF" for 5 seconds. Repeat this cycle 3 times to purge air from the lines, then start the engine on the 4th cycle.
Q: Does the chassis filter include a new water-in-fuel (WIF) sensor or drain bowl?
A:No. The primary chassis filter features precision-threaded ports designed to accept your factory reusable WIF sensor and drain bowl. Simply transfer your factory sensor and bowl to the new filter during service.
Q: Can I upgrade this dual-fuel kit to a complete maintenance bundle?
A: The natural next step is adding the oil filter — the 2013-2018 Dual Fuel + Oil 3-Filter Kit builds on this exact fuel pair. From there, the 4-filter and 5-filter kits add air and cabin filters for the no-compromise service.
