Drop-In Series Fuel System for 03 to 07 Dodge/RAM Cummins 5.9L - FASS - DIFSRAM2001

The FASS Drop-In Series Diesel Fuel System was engineered by FASS to be the most effective filtration solution for the 5.9L Cummins. Backed by our limited lifetime warranty, the Drop-In Series Fuel System protects your 5.9L Cummins from the issues caused by fuel contamination.

If you drive a Ram with a Cummins diesel engine and want better fuel filtration, improved reliability, and injector protection without adding an external frame-mounted pump, the FASS Drop-In Series Fuel System is the perfect solution.

Designed as a direct replacement for the factory engine fuel filter, the Drop-In Series delivers cleaner fuel, better water separation, and consistent fuel supply while retaining a factory-style installation.

Fits: 2003-2007 RAM 2500 and RAM 3500 5.9L Cummins (With AN in-Tank lift pump). 2003-2004.5 trucks Must have been retrofitted with an in-tank lift pump in order to utilize this product.

Please Note: This is not A Lift pump! This is an air separation/filtration system that utilizes your factory lift pump.

Please Note: Installation of this kit on a cab and chassis may require modifications. Drop-In Fuel Systems are a plug-and-play filtration upgrade and are not compatible with our Fuel Sump Kit. No additional items are needed for installation. This plug-and-play filtration system retains the Cummins OEM in-tank fuel pump.
