The Pureflow AirDog II 5G 165GPH A7SABD427 lift pump, or Fuel Preporator, is a must have upgrade for your 2019+ 6.7L 24V Cummins. The fuel system on your Cummins is the heart of the vehicle’s performance and reliability. This low pressure (preset at 13-15 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 included Fuel Module Upgrade Kit installed in the tank bypassing the factory in tank fuel pump. The pressure side line connects directly to the side of the factory fuel filter housing. The Air/Vapor return is sent back to the tank through the factory 3/8” suction line once the module is modified.
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.
