This conversion kit was specifically designed to save money on fuel filters and make fuel filter changes super easy on your 2019-2022 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 plug and play! It will connect directly to the factory fuel lines and bolts directly in place of the factory filter head.

This kit also includes a pigtail to eliminate the WIF light in 2019 and newer trucks. The WIF circuit on these trucks is designed to sense anytime the WIF sensor is not connected. Therefore, we have a factory OE plug that includes the proper circuitry to eliminate this issue.

We have 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!

Features Include:

  • Direct OE Plug & Play Install
  • Includes OE WIF sensor pigtail
  • All billet aluminum construction
  • Stainless threaded filter inserts
  • AN style O-ring fittings
  • Wide range of filter interchanges
  • Optional Fuel Heater Kit
  • Optional OE Engine Mounted Filter Delete Block


NOTE: Most other fuel filter delete blocks will not work to eliminate the factory engine mounted fuel filter housing for this application. Our optional filter housing delete 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.

An add-on part for the kit will be an optional fuel heater. The fuel heater will include an adapter harness that allows it to plug into the factory harness and utilize the factory fuel heater circuit. Click Here

NOTE: If you have a 2019 – 2023 DRW, there will be an exhaust hanger bracket modification upon installation. The hanger bracket will be in the way of  water separator filter. You are able to bend that hanger bracket out of the way for clearance. If you have either of these truck variations, all extra extensions and parts you could possibly need will be included in your kit!!


Note: If you have a 5500 Cab & Chassis this conversion kit will not work on your truck. The frame rail will be in the way of the conversion kit. We have a 5500 Cab & Chassis CAT fuel filter conversion kit, the part number you need is GRD67CM3028!! If you have any questions please give us a call!!
