AirDog II 4G Series

AirDog II-4G Demand Flow Technology DF-165-4G Fuel Pump Kit | 01-10 Chevy Duramax

Chevy and GMC trucks with the Duramax Engine do not have a fuel lift pump from factory which greatly increases the strain on the High Pressure CP3 injection pump. It also increases the amount of entrained air and vapor going through the injectors. This greatly decreases the life of the injector as the air and fuel mixture will ignite as it passes through the injector nozzle creating a torch effect and eroding the nozzle. Over time this will effect the spray pattern and fuel atomization of the nozzle. The installation of an air separation system is hands down one of the best improvenents for the longevity of the Duramax fuel system.

AirDog® II-4G is designed to operate at flows and pressures beyond the maximum requirements of the engine. It receives fuel under vacuum from the fuel tank containing entrained air/vapor, particulate contaminates and unknown quantities of water.

The fuel passes through the water separator which removes the large particulate contaminates that could damage or jam the gear rotor 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 fuel 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 AirDog® II-4G the separated air/vapor is discharged from the filter and back to the fuel tank through the Primary Air/Vapor Discharge Port.

The fuel passing through the filter media is now free of contaminates and power robbing air/vapor. At pressures and flows able to meet the needs of the engine, it exits the fuel filter through two passageways. First, the fuel for the engine passes into the fuel pickup tube and on to the engine. Then, the excess fuel not needed by the engine recycles internally through the pressure regulator back to the water separator.
