Extra Info:

This is the AirDog II-4G DF-165 fuel system for the 1989-1993 12V VE-44 5.9L 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. The pressure side connects directly into the side of the injection pump, bypassing the factory fuel filter housing and factory mechanical fuel pump. 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
