AirDog A4SPBD005 FP-150 2004.5-2018 Dodge Cummins Fuel Air Separation System

Sold out


Beginning in 2005, Dodge made a change that moved the factory lift pump from the side of the engine block into the fuel tank in order to allow the fuel to be instead of to aid in pump life longevity. While this change was a move in the right direction, the factory pump is still underrated especially for trucks that have been even slightly modified. This frame mounted lift pump will deliver 150 gallons per hour (GPH) of fuel, enough to support 500 all the way 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.
