This is the AirDog II-5G DF-220 fuel system for the 2004.5-2018 Dodge Ram Common Rail Cummins. This diesel lift pump mounts to the frame rail using the supplied sandwich plate mounting system. A 5/8" draw straw is used to pull fuel from the tank. The pressure side connects directly into the side of the injection pump, bypassing the factory fuel filter housing. The AirDog Air/Vapor return is sent back to the tank through the original suction fitting in the modified fuel module. This is a 220GPH (Gallon Per Hour) lift pump system for highly modified trucks. Check out our installation manual for a list of parts that are included with this kit.
