Please Note: THIS IS NOT A LIFT PUMP! This is an air separation and filtration system that utilizes your factory in-tank lift pump. 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. The system mounts in the factory location and may not fit aftermarket high-capacity fuel tanks; verify clearance before ordering. No additional items are needed for installation. This drop-in filtration system retains the RAM OEM in-tank fuel pump.
