Extra Info:

This is the AirDog II-4G DF-165 fuel system for the 2008-2010 6.4L Powerstroke. This system mounts to the frame rail using the supplied sandwich plate mounting system. The suction side hooks up to the factory suction line on the frame rail. The pressure side connects to the factory supply line on the frame rail. This fuel pump completely bypasses the factory fuel pump. The AirDog Air/Vapor return is sent back to the tank through a return ?Y? that splices the AirDog return into the factory engine return. This is a 165GPH (Gallon Per Hour) fuel system for moderately modified trucks.
