The AirDog II-4G A6SABD424 DF-165-4G Air/Fuel Separation System for your 1994-1998 Dodge 5.9L Cummins is the next generation in the fuel delivery system, resulting in a long lasting, efficient and quiet lift pump. The compact AirDog II-4G provides the most effective technology designed specifically for diesel pickups to remove water, particulates, vapor and entrained air from diesel fuel, all while increasing power and performance.
The new design of the patented AirDog II-4G features many innovative improvements for increased pump performance, less noise and less maintenance. The AirDog II-4G utilizes an intermediate pump shaft that moves the electric motor away from the fuel. This eliminates any potential for ”wet motors” due to a damaged or leaking seal. The motor’s self-aligning capability requires less maintenance and increases the systems endurance resulting in a longer pump life. The low amperage motor also provides longer drivability and contributes to a significant reduction in noise.
AirDog is proud to announce that the AirDog II-4G is the quietest fuel system in the diesel market!

AirDog® II-4G Fuel Air Separation System featuring Demand Flow Technology and Enhanced Features
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.
