The AirDog II-5G is an all in one premium fuel pump and filtration system for your 1999-2003 7.3L Powerstroke diesel. This system removes water, particulates, and entrained air from the diesel fuel. The entrained air that is separated from the fuel is returned to the tank through a small return fitting. The fuel is delivered to the engine at the correct pressure and flow rate to meet the demands of the engine under all operating conditions.
The AirDogII-5G DF-165 systems feature a built in adjustible diaphragm pressure regulator. All AirDog II-5G systems include a complete installation kit. The AirDog II-5G, for this particular application, is preset at 55-60 psi from the factory for a stock application. The regulator is adjustible up to 70 PSI so you can fine tune the system to perfectly match up to your current and future performance upgrades.
