68436631AA Fuel Water Separator for Ram 6.7L Cummins (2019-2024)

Every 15,000 miles (24,000 km) or 12 months, whichever comes first. Shorten the interval if the water-in-fuel indicator lights often or if the truck runs on high-water or biodiesel fuel.

It is the chassis filter. On 2019-and-newer Ram 6.7L Cummins trucks the fuel system runs two filters: the 68436631AA in the frame-rail housing and the 68157291AA in the engine bay. They are separate parts and are not interchangeable.

It fits 2019-2024 Ram 2500, 3500, 4500 and 5500 with the 6.7L Cummins diesel, and 2020-2023 Ram 1500, 2020-2024 Jeep Wrangler and 2021-2024 Jeep Gladiator with the 3.0L V6 EcoDiesel. Confirm model year and engine before ordering.

Yes. The element is supplied with its sealing O-ring. The housing (68358393AA) and the cover (68436815AA) are not included, only the cartridge element.

It is the particle size the multi-layer depth media is built to capture. That is the filtration stage that keeps fine sediment out of the high-pressure fuel pump and the injectors, which is why the chassis element is replaced on schedule.
