The Original Fuel Air Separation System

The AirDog Fuel Preporator, with the capability to provide fuel at flows and pressures beyond the maximum requirements of the engine, receives fuel under vacuum from the fuel tank containing entrained air/vapor, particulate contaminates and unknown quantities of moisture. The fuel passes through the water separator which removes the water and large particulate contaminates that could damage or jam the gearator fuel pump. The fuel, with only entrained air/vapor and tiny particulate contaminates remaining, enters the fuel pump.

The fuel, now under positive pressure flow, enters the filter. As the fuel passes through the filter media and the remaining particulate contaminates are caught and contained, the entrained air/vapor is also separated. Through the positive fuel air separation features of the patented Fuel Preporator the separated air/vapor is discharged from the filter through the Primary Air/Vapor Discharge Port and into the return to tank passage after the regulator. The fuel passing through the filter media (free of contaminates & power robbing air/vapor and at pressures and flows to meet the needs of the engine exits the fuel filter through two passageways. The fuel for the engine, passes into the fuel pickup tube and out to the engine).

The excess fuel not needed by the engine is released through the pressure regulator to combine with the air/vapor and foam as it returns to the fuel tank. The regulator controls the fuel pressure to the engine.

AirDog Benefits

The AirDog Fuel Preporator removes various contaminates, including entrained air/vapor, particulates and moisture, and removes excess fuel not needed by engines, allowing the fuel to flow through the regulator and return to the fuel tank. The separated air/vapor enters the return port after the regulator, allowing pure fuel to flow to the engine at a regulated positive pressure. A gerotor pump offers quiet, long lasting performance. Some benefits include:

  • Removes Air and Vapor from Diesel Fuel
  • Pure Diesel Fuel Reaching Engine
  • High Flow Rates of Fuel to Engine
  • Longer Injector Life
  • Increased Injection Pump Life
  • Increased Fuel Economy
  • Optimized Engine Performance
  • Increased Torque Output
  • Improves Throttle Response
AirDog Features
  • Small & Compact: Only 7"L X 10"T X 3.2"W
  • Single Piece Pump Body: Replaces the old 3 piece pump design reducing the number of parts, unit size, and weight. This results in a sleek, low profile pump assembly and eliminates the need for leaky, messy gaskets!
  • Mounts to frame: No Drilling required!

All-Inclusive Installation Kit includes:

  • Relay Control Wiring Harness
  • 1/2" Suction Tube (when required)
  • All Fuel Fittings Required

  • How long does the air dog pump usually last???

    Lupe Hernandez | 8/31/2020

    No way of having an exact answer, the Airdog has a 1 year upfront warranty, if you fill out warranty paper work it will make it life time.

  • 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.
