Product Details

Product Name:AirDog FP-150-4G 1998.5-2004 Dodge Cummins
Manufacturer: AirDog
Manufacturer Part #: A4SPBD104
Thoroughbred Diesel Part #: PFTA4SPBD104
Fitment Notes: 1998.5-2004 Dodge Cummins

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.


Reviews

  • Will this system allow the CP3 pump to pull enough fuel through it to keep the engine running enough to get to a safe stopping place or does it completely shut off the fuel flow if there is a problem with it ?

    Larry Clark | 9/9/2025
    • Yes, Airdog is a flow through pump
  • Will it work on trucks with the in tank fuel pump
