This is the AirDog II-5G DF-220 fuel system for the 2019 to 2021 Ram 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. This will bypass the factory in-tank lift pump. The pressure side connects directly into the side of the factory fuel filter housing. The AirDog Air/Vapor return is sent back to the tank through the factory 3/8” suction line once the module is modified. 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.
