The Pureflow AirDog II 5G 100 GPH A7SPBD252 lift pump, or Fuel Preporator, is a must have upgrade for your 1994-1998 12V 5.9L Cummins. The fuel system on a P-Pump Cummins is the heart of the vehicle’s performance and reliability. This low pressure (preset at 25-30 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 factory suction fittings in the fuel module. The pressure side connects to the side of the P7100 P-Pump bypassing the block mounted mechanical factory pump and fuel filter housing.
The II-5G Cummins fuel pump features a fully adjustable (7-55psi) integrated diaphragm pressure regulator. This regulator offers more consistent fuel pressure and allows for higher flow rates at pressure. It can also be boost compensated to battle any pressure drops under open throttle (boost compensation kits sold seperately). The AirDog 5G also includes an updated 12 gauge wiring harness with Metri-Pack 280 connectors, which allows for higher current flow without creating excessive heat.
