Extra Info:

This is the AirDog II-4G DF-100 fuel system for the 1998.5-2004 VP-44 and early CP3 5.9L Cummins WITH the in-tank fuel pump. 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
