Description

The AirDog II 4G 200GPH A6SABC112 Duramax Lift Pump Air/Fuel Separation sytem, or Fuel Preporator, is a top recommended upgrade for your aggressively modified 2001-2010 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 (8-10 psi) Duramax lift pump mounts to the inner frame rail using the supplied sandwich plate mounting system.  The suction/fuel supply sides hook directly up to the factory quick disconnect fittings in the fuel module.  The pressure side feeds the injection pump through the factory feed line on the frame making the install very straight forward. 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)

 

Over the life of your diesel pickup truck there may be unnecessary stress on your fuel system. High mileage and/or additional performance modifications such as a tuner or over size injectors can weaken your injection pump, or CP3. This will shorten the amount of running time you will get out of them in comparison to the stock fuel system. This may lead to a drop in performance, reliability, and fuel efficiency.

Things to Consider

Choosing to purchase and install an AirDog II-4G lift pump will strengthen, protect, and in most cases extend the life of the fuel system and related parts. The supplied fuel filter (FF100-2) will filter your fuel down to a 2 micron rating, and the water separator (WS100) will remove excess moisture from the fuel system.  This type of filtration surpasses the stock fuel filter’s capability.  The AirDog II-4G also helps by eliminating spray pattern disruption from air entering the diesel fuel system. The result is overall increased engine efficiency by keeping the injection timing where it should be thus allowing a more complete burn of the fuel entering the cylinder.

 

The AirDog II 4G 200GPH will solve the infamous P0087 & P1093 low fuel rail pressure codes associoted with high horsepower modifications by supplying your CP3 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 4G 200GPH 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 200GPH pump is designed for performance applications reaching up to 1,000 RWHP! Backed by a lifetime warranty.
