DESCRIPTION
Product Overview
- The Trucktok Dual-Stage Fuel Filter is purpose-built to integrate seamlessly with the redesigned top-load fuel filtration system on the latest-generation 6.7L Cummins engines. This innovative cartridge combines a 5-micron primary water separator with an ultra-fine 3-micron NanoNet™ secondary filtration element inside a single compact housing, delivering absolute fuel system protection in a single service step.
- Engineered with silicone-treated cellulose and advanced synthetic NanoNet™ microfiber media, this filter maximizes both critical water separation and sub-micron particulate capture to shield sensitive high-pressure common-rail injectors from premature wear. Precision OE-specification dimensions guarantee a reliable, leak-free seat within the top-load housing, and the kit includes premium replacement O-rings for a complete, hassle-free installation.
Key Features
- Combines a silicone-treated cellulose outer barrier with a premium 3-micron synthetic NanoNet™ inner microfiber media for highly effective, multi-layered filtration.
- Includes both the 5-micron primary and 3-micron secondary filtration elements to fully service the top-load fuel system in a single routine maintenance step.
- Maximizes water separation efficiency from diesel fuel, safeguarding sensitive high-pressure common-rail injection pumps and injectors from corrosive moisture and abrasive wear.
- Deeply pleated, high-surface-area media ensures exceptional dirt-holding capacity and unrestricted fuel flow, preventing fuel starvation from freezing winter cold-starts to heavy summer towing.
Replacement Interval
- Replace every 15,000 miles or 12 months (whichever comes first) under normal conditions. Shorten to every 10,000 miles under severe-duty conditions (heavy towing, high idling, or dusty environments) to ensure continuous protection for high-pressure injectors.
FAQ
Q: What changed with the redesigned fuel filter system on the latest-generation Cummins?
A: The updated setup replaces the old two-filter system (frame-rail + engine-bay) with a single, engine-bay top-load cartridge. This single assembly integrates both the 5-micron primary and 3-micron secondary elements, reducing your routine maintenance to just one filter change.
Q: Why is this filter more expensive than previous-generation fuel filters?
A: This cartridge (matching OE 68677800AA / FK11008NN) contains both filtration stages in one unit—effectively replacing two separate filters you previously had to buy individually. It also upgrades to premium synthetic NanoNet™ microfiber media for superior injector protection.
Q:Is the installation procedure different for this new top-load system?
A: Yes, and it's much easier. The housing is accessed entirely from the top of the engine bay (no crawling under the truck). Simply unscrew the cap, swap the cartridge and O-ring, and hand-tighten. If it doesn't slide in smoothly, rotate it slightly to align the housing tabs.
Q: Does this filter work on deleted or tuned 2025-2026 trucks?
A: Yes. The NanoNet™ media handles high flow rates exceeding stock demands with zero restriction. Maximum filtration is even more critical on modified engines, as increased injection pressures make fuel systems far more sensitive to water and particulate damage.
Q: Should I pair this with the new-style oil filter for a complete service?
A: The 2025-2026 Ram uses an all-new oil filter design, and replacing fuel and oil together keeps your maintenance on one schedule. The 2025-2026 Dual Fuel + Oil Kit bundles this fuel filter set with the matching 68677810AA oil filter in one order.
