Description:

The factory block mounted lift pumps found on the 1998.5-2004.5 Cummins have proven themselves as being nothing better than a temporary Band-Aid. Further, as the lift pumps failed, it would cause premature failure of the injection pump, a very expensive repair. While Dodge began retrofitting fuel pumps from the block to inside of the fuel tank, it has been shown that this conversion is better than the original units, but still not adequate, especially for those that have made any performance upgrades whatsoever. This pump will deliver 150 gallons per hour (GPH) of fuel, enough to support 500 to 800 rear wheel horsepower.
  • Supports 500 to 800 Rear Wheel Horsepower
  • Flows 150 Gallons Per Hour
  • Preset at 15-17 PSI


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 gearator pump offers quiet, long lasting performance.
