The Pureflow AirDog II 5G 165 GPH A7SABF589 lift pump, or Fuel Preporator, is a must have upgrade for your 2011-2016 6.7L Powerstroke. The fuel system on your 6.7L diesel truck is the heart of the vehicle’s performance and reliability. This high flow and high pressure lift pump is preset at 65psi right out of the box. The II-5G features a fully adjustable (up to 75psi) 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-165 Powerstroke fuel pump mounts to the inner frame rail using the supplied sandwich plate mounting system. The suction/fuel supply side hooks directly up to the factory lines on the frame rail. The pressure side line connects directly to the injection pump feed line and the air/vapor return is sent back to the tank through a return “Y” that ties the AirDog return to the factory engine return. This pump is designed to replace the factory high pressure pump. You can download the full PDF Installation manual HERE for a more in depth look at the installation process and a full parts list.
