Description
FASS Drop-In Series Fuel System – For 2003 to 2024 Dodge/RAM Cummins 5.9L / 6.7L
Please Note:THIS IS NOT A LIFT PUMP! This is an air separation/filtration system that utilizes your factory lift pump.
Fits: 2003-2007 RAM 2500 & 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:Installation of this kit on a cab and chassis may require modifications. Drop-In Fuel Systems are a plug-and-play filtration upgrade andare not compatiblewith 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.
The FASS Drop-In Series Diesel Fuel System was engineered by FASS to be the most effective filtration solution for the 5.9L and 6.7L Cummins. Backed by our limited lifetime warranty, the Drop-In Series Fuel System protects your 5.9L or 6.7L 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.
