Diesel fuel contains varying degrees of entrained air in the form of foam on the surface or suspended in the bulk fluid as tiny bubbles. Additionally, fuel is driven into the fuel pump by atmospheric pressure, which is usually only enough pressure flow to fill the pump at idle speeds. Consequently, at higher operating RPM's , the stock pump cavitates producing vapor. Air and vapor are compressible. The presence of air/vapor in the fuel injector delays the pressure build-up. This delays the injection, resulting in Retarded Injection Timing. Retarded injection timing in a diesel, just like bad spark plugs in a gasoline engine, causes lost power, poor fuel mileage, and an increase in exhaust emissions. Retarded Injection Timing caused by air/vapor is the primary source of the rough idle, lost power, increased fuel consumption and excessive exhaust emissions of the diesel engine. Air/vapor in the injector can also cause permanent damage in the form of galling and pitting of the barrel/plunger assembly and tip erosion. The conventional vacuum feed fuel supply system does nothing to remove entrained air from the fuel. In fact, it only makes things worse. As the filter plugs with use, the already inadequate fuel flow to the engine is further reduced, increasing cavitation and retarding injection timing even more.


  • I have 95' GM 6.5 turbo diesel. Stock engine. I tink the lift pump is time to replace,wat your recommendation

    Eliezer Ramirez | 9/9/2021

    The Air Dog 100 GPH  will support 500hp. the 150gph will support up to 800hp.

  • my 2002 ford 7.3 has vapor locked in the past with my air dog2 and is now acting up again as if the motor is starving for fuel and throwing an error code p1316. and yes it has new filters. any tips for this problem?

    Rod Skaare | 10/24/2020

    We are going to require some more information. Please call our tech support line.

  • If I daily drive my stock truck will running an AirDog 150 or AirDog II 165 4G hurt anything?

    Brad Smith | 5/22/2019

    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.

  • What is the difference between and Original AirDog and AirDog II 4G?

    Austin Davis | 5/22/2019

    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

  • What is the difference between the AirDog 100 and AirDog 150?

    Shawn Kelley | 5/22/2019

    Physically there are no differences. The units are the exact same size. The AirDog  100 is a 2000 r.p.m. motor and has a flow rate of 100 gallons. The AirDog 150 uses a 3000 r.p.m. motor and has a flow rate of 150 gallons per hour. Also, depending on the application, the actual installation on the vehicle will differ as well. For Dodge trucks with an in-tank fuel pump, both the 100 and 150 systems will require you to drop the tank and install a suction tube.

  • What kits will require dropping the tank or installing a suction tube?

    Bob Turner | 5/22/2019

    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

  • What AirDog pump do I need for my truck?

    Dennis Schwartz | 5/22/2019

    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.
