This is the AirDog® I FP-150-4G fuel system for the 2004.5-2018 Dodge Ram with the Common Rail Cummins. This diesel lift pump mounts to the frame rail using the supplied sandwich plate mounting system. A 1/2" draw straw is used to pull fuel from the tank. The pressure side connects directly to the CP3 injection pump, bypassing the factory fuel filter housing. The AirDog® Air/Vapor return is sent back to the tank through a filler neck tee. This is a 150GPH (Gallon Per Hour) lift pump system. Check out our installation manual for a list of parts that are included with this kit.
