The Pureflow AirDog II 5G 100GPH A7SPBD253 lift pump, or Fuel Preporator, is a must have upgrade for your 1998.5-2004 24V 5.9L Cummins. The fuel system on a Cummins 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 factory quick disconnect fittings on the fuel module. The pressure side connects directly to the VP44 or CP3 injection pump bypassing the factory block mounted pump and fuel canister.
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.
