The Pureflow AirDog II 5G 220 GPH A7SABD529 lift pump, or Fuel Preporator, is a must have upgrade for your 04.5 -18 5.9/6.7L Cummins. The fuel system on your 24V Cummins is the heart of the vehicle’s performance and reliability. This high flow and low pressure lift pump is preset at 17psi 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 connects directly into the side of the injection pump, bypassing the factory fuel filter housing.   The injection pump return is tied into the engine return to eliminate the need for the factory filter head.  The AirDog air/vapor return is sent back to the tank through the original suction fitting in the modified fuel module.   You can download the full PDF installation manual HERE for a more in depth look at the installation process and a full parts list.

 

This AirDog II 5G 220GPH Cummins lift pump is recommended for trucks that have an aggressively upgraded fuel system (meaning stock to larger injectors and oversized injection pump; will also support aggressive tuning). The DF-220 pump is designed for performance applications over 1000 RWHP! Backed by a lifetime warranty.

 

The AirDog II-5G DF-220 for the 04.5-18 24V Cummins is engineered with the most proven, quiet and reliable motor technology on the market.  It also retains the “demand flow” capabilties of the previous AirDog II systems.  This means that is has a constant supply of clean, pure fuel available for your injector pump at all times.  Any fuel not used by the engine is simply recycled back to the tank, so it will never “over-fuel” your system (see How It Works).  The II-5G features larger 3/4-16 O-ring boss inlet and outlet ports.  A 7/16-20 (-4) low-flow return is used to prevent aeration in the fuel returned to the tank.  The II-5G A7SABD529 uses the same better-than-OEM fuel filter (FF100-2) and water separator (WS100) as the previous AirDog II models.  Pureflow AirDog products are manufactured in Shelbyville, Indiana by a team of skilled workers with unsurpassed attention to detail and using the most stringent quality assurance.
