AirDog II-4G, DF-100-4G 2004.5-2018 Dodge Cummins

This is the AirDog II-4G DF-100 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 100GPH (Gallon Per Hour) fuel system for stock fuel trucks. Check out our installation manual for a list of parts that are included with this kit.The solution for diesel performance is the AirDog ® Fuel Preporator ®. It is the only filtration delivery system that separates air from the fuel, as well as water and particulates.

This fuel system maintains the proper pressure flow to the transfer pump, eliminating cavitation and vapor. The Fuel Preporator significantly improves diesel engine performance and is one of a very few aftermarket performance modifications to be CARB certified and approved for sale and use in California.
