Tired of over-priced fuel filter service costs and questionable filter options? Our direct replacement under bed fuel filter base for the 2019-2024 Ram with 6.7L Cummins allows you to convert to a more convenient Donaldson spin-on filter and will lower your ongoing filter maintenance costs.  This kit replaces the factory plastic fuel filter housing with a new anodized billet aluminum filter base, Donaldson spin-on canister style filter,  Water-In-Fuel (WIF) sensor, and integral high-flow fuel heater option.

Fully assembled filter base is ready to install!
