This conversion kit was specifically designed to save money on fuel filters and make fuel filter changes super easy on your 2013-2018 Ram/ Cummins truck. It includes Cat filters but can be easily interchanged to any major brand filter. With this conversion kit you are no longer stuck to the expensive OE style filters.

It installs in place of the rear fuel/water separator but features both a primary and secondary filter. This eliminates the need for a filter on the engine. Now both filters are easily accessible from underneath the truck and no longer require dealing with any fuel mess under the hood! The factory filter assembly on the engine can now be eliminated helping to clean up the engine bay or be left there as a precautionary filter that now no longer needs changed as often.

This kit is 100% plug and play! It will connect directly to the factory fuel lines and bolts directly in place of the factory filter head.

We have also incorporated a threaded port that allows for a fuel heater assembly (sold separately). Our fuel heater kit comes with a direct connect plug that utilizes the factory fuel heater circuit. No cutting or splicing wires!



  • Direct OE Plug & Play Install
  • All billet aluminum construction
  • Stainless threaded filter inserts
  • AN style O-ring fittings

  • 2013-2018 Ram 2500/3500 6.7L Cummins



  • Most other fuel filter blocks will not work to eliminate the factory engine mounted fuel filter housing for this application. Our optional filter housing block is designed specifically to connect ALL factory fuel supply and return lines where most others are designed to only connect the return lines and not the factory supply lines.
