The AirDog II 5G 220GPH A7SABC514 Duramax Lift Pump Air/Fuel Separation system, or Fuel Preporator, is a top recommended upgrade for your aggressively modified 2011-2014 Chevy/GMC Duramax diesel. The fuel system on your Duramax diesel is one of the most important systems when it comes to performance and reliability. This high flow and low pressure pump is preset to 8-10psi right out of the box. The II-5G 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 separately).
The II-5G DF-220 Duramax lift pump mounts to the factory frame standoff in front of the fuel tank using our cradle bracket. The suction/fuel supply sides hook directly up to the 5/8″ draw straw installed in the tank. The pressure side feeds the injection pump through a direct connection to the 1/2″ factory feed line on the frame. The air/vapor return is sent back to the tank through the factory 12mm suction line once the module is modified. Due to the fact the Duramax does not have a factory lift pump, these trucks usually see the most benefit from an AirDog lift pump fuel system. (see How It Works). You can download the full PDF Installation manual HERE for a more in depth look at the installation process and a full parts list.
The AirDog II 5G 220GPH will solve the infamous P0087 & P1093 low fuel rail pressure codes associated with high horsepower modifications by supplying your CP4 injection pump with fuel, rather than your injection pump doing most of the work pulling the fuel up from the tank. This positive supply of purified fuel being fed to your injection pump will also add performance, throttle response, and longevity to your vehicle.
This AirDog II 5G 220GPH Duramax lift pump is recommended for trucks that have an aggressively upgraded fuel system (meaning stock to larger injectors and injection pump; will also support aggressive tuning). The 220GPH pump is designed for performance applications reaching over to 1,000 RWHP! Backed by a lifetime warranty.
The AirDog II-5G DF-220 for the 11-14 Duramax 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. 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 A7SABC514 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.
