AirDog® II-4G AirDog® II-4G Removes Entrained Air/Vapor From Ford Powerstroke Diesel Fuel Improving Engine Performance The next generation in the fuel delivery system.The patented AirDog® II-4G has been quality engineered to remove entrained air and water vapor from diesel fuel for your Ford Powerstroke. The result is a compact, long lasting, efficient, and quiet fuel system made with superior quality.Advancing the AirDog® Tradition with the 4th Generation Fuel System!The AirDog® II-4G system improves engine performance by:
No, it will not hurt anything. With the Original AirDog’s High Flow return all excessive fuel not being used by your truck will be returned to the tank. When running the AirDog II 4G the Demand flow only allows the pump to send what fuel is needed to the injection pump, and all other fuel is recirculated internally in the base returning it to the suction side of the pump.
The AirDog II 4G aside from having the adjustable regulator, the pump and base assembly are designed different internally. The pump assembly has a Dual Inlet design allowing more fuel to flow into the Gerotor, this allows the pump to increase volume without having to work any harder. The base on the AirDog II is also much different. Internally the fuel is redirected through passageways after being pressurized, this allows less fuel to be returned to the tank and more fuel to be held in the filters for a true “On Demand” system. An intermediate shaft was also incorporated to completely separate the electric motor from fuel path along with an additional two bearings to reduce drag and increase reliability and lifespan of the AirDog II 4G
All Original AirDog 150, AirDog II 200 Systems and AirDog II 165 Dodge Systems. Any truck that is equipped with an in tank fuel pump will require a suction tube or module upgrade kit
Original AirDog and AirDog II 100 units are recommended for up to 500 horsepower. Original AirDog 150 and AirDog II 165 units are recommended for horsepower up to 1000. AirDog ® II 200 units are recommended for anything that exceeds 1000 horsepower.
