Product Description

FASS Drop-In Series Diesel Fuel System. Engineered to be the most effective filtration solution for the 6.7L Cummins, protecting the injection system from water, air/vapor, and debris down to 2 microns. Retains the Cummins OEM in-tank fuel pump for a true plug-and-play install, requiring no cutting, wiring, or additional modifications -- and is the only drop-in filtration system that retains full functionality of the Water-In-Fuel (WIF) sensor.

Industry-leading water removal capabilities, 3rd-party proven to exceed 99%, are reinforced by the unique design of the Extreme Water Separator (XWS). If the XWS reaches capacity, it acts as a dam, shutting down the truck and preventing major destruction of fuel system components. Performance Radius Cuts (PRC), an advanced machining technique, create smooth-flowing cuts within the filtration system to prevent the reintroduction of air and vapor, unlike lesser competitors that commonly use T-Bone and square 90-degree fittings.

Fits 2019-2023 Ram 2500 and 2019-2024 Ram 3500, 6.7L Cummins. Mounts in the factory water separator location -- verify adequate space if running an aftermarket fuel tank. Electric heater options available separately for cold weather reliability. Can be installed in under an hour. Backed by FASS's limited lifetime warranty.
