PureFlow AirDog Fuel Preporator

The AirDog II-4G 200PH A6SABC114 Air/Fuel Separation lift pump, or Fuel Preporator, is a must have upgrade for your aggressively modified 2011-2014 LML Duramax. The diesel fuel system on your LML is the heart of the vehicle’s performance and reliability. This high flow and low pressure (8-10psi) LML lift pump mounts in front of the tank to the frame jig. 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 the fuel system. High mileage and/or additional performance modifications such as a tuner or over size injectors may weaken your injection pump, or CP4, in a shorter amount of time than with the stock fuel system. As a result, your performance, reliability, and fuel economy may suffer. However, by installing an AirDog II-4G lift pump, you will strengthen, protect, and in most cases extend the life of your 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 will also help your truck by eliminating spray pattern disruption from air entering your 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.

Fixes some common engine codes

The AirDog II-4G 200GPH solves 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.

Recommended Use

This AirDog II 4G 200GPH LML lift pump is recommended for trucks that are highly modified. This will supply enough fuel to support rides making 1,000+ RWHP! Don’t forget all PureFlow AirDog pumps are backed by a lifetime warranty.
