This is the Raptor-4G RP-150 fuel system for the 2005 and UP 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 fuel filter housing on the engine block. These pumps are internally regulated and do not require a return line. This is a 150GPH (Gallon Per Hour) fuel system for moderately modified trucks.
