AirDog® Has the Solution
for Your Diesel Fuel Systems

One of the major hindrances to consistent and fuel-efficient horsepower in your vehicle’s diesel fuel system is air and vapor in the fuel.

The Diesel Fuel System

Another major contributor to lost efficiency in the diesel fuel system is pump cavitation, largely caused by the negative pressure (vacuum) created by the engine transfer pump pulling fuel from the fuel tank. Drawing fuel under vacuum means the fuel pump is pulling at negative pressure, which causes the formation of vapor in fuel, and can starve the engine for fuel, especially during hard accelerations. When air or vapor is forced into the injectors, the lack of diesel fuel also means the lubrication needed to maintain healthy fuel injectors is missing. The result is metal on metal contact which shortens the functional life of your injectors. The AirDog® integrated fuel pump works as a lift pump, drawing fuel from the tank, relieving the burden of “draw” on the engine transfer pump, and feeding the engine pump with adequate positive pressure. The AirDog® prevents vapor from forming in the delivery system by feeding appropriate positive pressure to the engine’s system.

To eliminate and remedy these problems, AirDog® Heavy Duty Diesel Fuel Systems has created the first-ever, and still the best, diesel fuel system that removes air, vapor, and contaminants from the fuel before it gets to the injectors.
