AirDog® Heavy Duty Diesel Fuel Systems optimize the diesel fuel delivery system for peak efficiency and performance. How do we do that? Featuring a state-of-the-art integrated Demand Flow fuel pump, the AirDog® pulls fuel from the tank, and removes virtually all contaminants from the diesel fuel supply – including moisture, particulates, and entrained air and vapor – ensuring that a pure supply of fuel is delivered to your OEM fuel system under optimal pressure.

Applications for AirDog® HD systems include heavy- and medium-duty trucks, agriculture, off-highway and excavation, mining, marine, and more. AirDog® HD installation kits are available for most popular commercial diesel engine models on the market today, including Caterpillar, Cummins, Detroit, International/Navistar, Mack, PACCAR, and Volvo. AirDog® HD also offers Universal installation kits that enable the system to adapt to virtually any diesel engine. If you have a diesel engine, there’s an AirDog® for that!
