Optimize your 2003-2004 Dodge Ram 5.9L Cummins with the AirDog Raptor 4G RP-100 fuel system, a 100GPH (Gallon Per Hour) lift pump for stock trucks without an in-tank factory fuel pump. 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, while the pressure side integrates with the fuel filter housing on the engine block. Internally regulated with no return line needed, this pump simplifies installation. Ideal for reliable fuel delivery in stock Dodge Cummins engines, this kit includes all necessary parts—check the installation manual for details.
