Ford Powerstroke Diesel AirDog II 4G Fuel Pumps

Ford Powerstroke Diesel AirDog® II-4G Fuel Air Separation Systems


The PureFlow AirDog® II-4G fuel air separation system incorporates the latest technology available to provide the cleanest diesel fuel possible for Powerstroke. at superior flow rates and pressure. The purified diesel fuel delivered to your Ford Powerstroke Diesel engine is provided at superior flow rates and fuel pressure which ensures the highest rate of engine performance.

The AirDog 2-4G fuel delivery system is an efficient, long lasting and quiet lift pump. The compact AirDog II-4G provides the most advanced technology designed specifically for diesel pickups to remove water, vapor, particulates and entrained air from diesel fuel while proving increased engine performance.

The new design of the patented AirDog II-4G features many innovative improvements for increased pump performance. This results in less noise and less maintenance. The AirDog 2-4G features an intermediate pump shaft that moves the electric motor away from the fuel, effectively isolating it. This eliminates any potential for “wet motors” due to a damaged or leaking seal. The motor’s capability to self-align requires less maintenance and increases the systems endurance, resulting in a longer pump life. The low amperage motor also provides a significant reduction in noise, and longer drivability. The PureFlow AirDog® II-4G fuel pump Replace the OE lift pump on your Powerstroke Diesel engine.

The AirDog 2 4G Fuel Preporator® lift pumps are available for the following Ford Powerstroke diesel engines.
