AirDog PureFlow 2011-2014 Chevy Duramax FP-100 Fuel Pump

AirDogSKU: A4SPBC086

Sale price$670.00 USD


From the factory, your Duramax is not equipped with a low pressure lift pump. Rather, it puts all of the load on the CP4 injection pump to inevitably the fuel from the tank. To make matters worse, it has been proven that the move in 2011 to a CP4 from the original, higher output CP3 from previous model year Duramax's has led to numerous failures. By adding a lift pump with added filtration, such as this model Airdog, you will ensure that your engine and injection pump are properly fed enough fuel while supporting stock to 500 rear wheel horsepower applications.

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
  • 100 GPH @ 8-10 PSI Supports Stock to 500 Rear Wheel Horsepower
