This is the AirDog II-4G DF-200 fuel system for the 2019 and UP Ram Cummins. This diesel lift pump mounts to the frame rail using the supplied sandwich plate mounting system. A Fuel Module Upgrade Kit is installed in the factory fuel basket to pull fuel through a, factory-style, 1/2″ bulkhead fitting. 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 200GPH (Gallon Per Hour) lift pump system for stock fuel trucks. Check out our installation manual for a list of parts that are included with this kit.
