The Pureflow AirDog 4G 100GPH A4SPBD153 is the original proven Air/Fuel Separation Cummins lift pump or Fuel Preporator. A lift pump system is a must have for your 1998.5-2004 24V Cummins diesel. The fuel system on a 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 side connects directly to the supplied 1/2″ draw straw suction tube installed in the tank bypassing the factory pump. The pressure side connects directly to the side of the VP44 or CP3 bypassing the factory fuel filter housing. The air/vapor return is sent back to the tank through a filler neck tee.
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.
