The Pureflow AirDog 4G FP-100 GPH A4SPBD136 is the original proven Air/Fuel Separation Cummins lift pump or Fuel Preporator. A lift pump system is a must have for your 1989-1993 12V 5.9L Cummins diesel. The fuel system on your diesel truck is the heart of the vehicle’s performance and reliability. This low pressure (preset at 10-13 psi) Cummins lift pump mounts to the inner frame rail using the supplied sandwich plate mounting system. The suction/fuel supply sides hook directly up to the factory quick disconnect fittings on the fuel module. The pressure side connects directly to the VE-44 which bypasses the factory mechanical pump and 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.
