The Pureflow AirDog II 5G 220 GPH A7SABD530 lift pump, or Fuel Preporator, is a must have upgrade for your 2019-2021 6.7L Cummins. The fuel system on your 6.7L diesel truck is the heart of the vehicle’s performance and reliability. This high flow and low pressure lift pump is preset at 13-15psi right out of the box. The II-5G features a fully adjustable (up to 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 II-5G DF-220 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 5/8″ draw straw installed in the fuel tank. The pressure side line connects directly into 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. This pump is designed to replace the factory in-tank pump.
