The AirDog II 5G 165 GPH A7SABD525 lift pump, or Fuel Preporator, is a must have upgrade for your 1998.5-2004 24V 5.9L 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 side hooks directly up to the supplied Fuel Module Upgrade Kit. The pressure side line connects directly to the side of the VP44 or CP3 injection pump. The air/vapor return is sent back to the tank through the factory 3/8” suction line once the module is modified. This kit will bypass the block mounted (98.5-02), in-tank (98.5-02) or frame rail mounted (03-04.5) stock pump and factory fuel housing. This lift pump can be used in conjunction with a fuel tank sump (DRX09SMP).
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.
