The Pureflow AirDog II 5G 220 GPH A7SABF595 lift pump, or Fuel Preporator, is a must have upgrade for your 2008-2010 6.4L Powerstroke. The fuel system on your 6.4L diesel truck is the heart of the vehicle’s performance and reliability. This high flow and low pressure lift pump is preset at 10psi right out of the box. The II-5G features a fully adjustable (7-70psi) 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 Powerstroke lift pump mounts to the inner frame rail using the supplied sandwich plate mounting system. The suction/fuel supply side hooks directly to the 5/8″ draw straw installed in the fuel tank. The pressure side line connects directly to the injection pump feed line on the frame rail. The air/vapor return is sent back to the tank through a return “Y” that splices the AirDog return into the factory engine return. This pump is designed to bypass the factory pump.
