Description

The AirDog II 4G 165GPH A6SABC108 Air/Fuel Separation lift pump, or Fuel Preporator, by Pureflow Technologies is a must have upgrade for your 1992-2000 6.5L GM Diesel. The fuel system on your diesel truck is the heart of the vehicle’s performance and reliability. This low pressure (8-10 psi) GM 6.5L Diesel 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 suction line quick disconnect fittings. The pressure side connects to the factory injection pump feed line bypassing the factory frame rail mounted pump, making the install very straight forward.

 

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 oversized injectors can weaken your injection pump in a shorter amount of time than with the stock fuel system. This may result in a drop in performance, reliability, and fuel economy.  Installing 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) and water separator (WS100) filter your fuel down to a 2 micron rating, which surpasses the stock fuel filters filtration 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. (see How It Works)

 

The AirDog II 4G 165GPH will solve the infamous P0087 & P1093 low fuel rail pressure codes.  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 165GPH is recommended for GM diesel trucks that have a stock to aggressively upgraded fuel system (meaning stock to larger injectors and injection pump; will also support aggressive tuning). Perfect fit for daily drivers to performance applications reaching up to 1,000 RWHP! Backed by a lifetime warranty.  (see How To Choose A Lift Pump)
