This is the Raptor-4G RP-100 fuel system for the 1989-1993 VE-44 12V Cummins. This system mounts to the frame rail using the supplied sandwich plate mounting system. The suction line connects to the factory suction fitting on top of the fuel module. The pressure side connects directly into the side of the fuel filter housing on the engine block. These pumps are internally regulated and do not require a return line. This is a 100GPH (Gallon Per Hour) fuel system for stock fuel trucks.
