This is the Raptor-4G RP-150 fuel system for the 2008-2010 Ford 6.4L Powerstroke. This system mounts to the frame rail using the supplied sandwich plate mounting system. The suction line connects to the factory suction fitting on the frame rail. The pressure side connects directly into the factory feed line to the factory fuel filter and injection pump. 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.
