This is the AirDog II-4G DF-165 fuel system for the 2004.5-2018 Common Rail Cummins. This system 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 injection pump, bypassing 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 165GPH (Gallon Per Hour) fuel system for moderately modified trucks. Check out our installation manual for a list of parts that are included with this kit.
