The Original AirDog 4G 100GPH A4SPBD102 is the original proven Air/Fuel Separation Cummins lift pump or Fuel Preporator. A lift pump system is a must have for your 2005-2018 5.9L and 6.7L Cummins. The fuel system on your diesel truck is the heart of the vehicle’s performance and reliability. This low pressure (preset at 15-17 psi) Cummins lift pump mounts to the inner frame rail using the supplied sandwich plate mounting system. The suction/fuel supply sides hook up to the supplied 1/2″ draw straw installed in the fuel tank bypassing the factory in tank pump. The pressure side lines connects directly to the CP3 bypassing the factory fuel filter housing.
The AirDog FP-4G Cummins fuel pump incorporates the proven, quiet, and reliable 4G motor featured in the AirDog II systems. This 4-bearing motor technology is paired with the original FP high flow return base and pump assembly to maintain the proven benefits and features of the Original AirDog model.
