About This Product
The AirDog A4SPBC189 FP-150-4G Air/Fuel Separation System from XDP is the perfect upgrade for the fuel system on your 2011–2014 GM 6.6L Duramax LML (Moderate To Extreme).

This AirDog system combines their traditional non-adjustable/high flow return base with the 4G motor they have been utilizing for years with great success. By maintaining this basic architecture, AirDog is able to offer a cost-effective system with a tried-and-true and reliable motor design.

When you improve the components and performance of your diesel engine, better fuel flow is required. Higher fuel flows result in more vacuum at the fuel pump and agitation in the fuel tank. The engine's performance suffers as a result of more air and moisture entering the fuel system. Air and vapor can also cause the injector barrel/plunger assembly to gall, pit, and have its tip eroded. By removing air from the gasoline, the AirDog protects your injectors from long-term damage and ensures that your engine runs as it should. The AirDog also provides the fuel pressures and flows your diesel engine needs to run at its best.

This system was created by AirDog to remove water, pollutants, vapor, and entrained air from diesel fuel. This lift pump and filter system is necessary to provide a steady flow of clean fuel to your engine.

The AirDog draws fuel from the fuel tank that contains entrained air/vapor, particle contaminants, and unidentified amounts of moisture. The fuel passes through the water separator, which removes water and large particle pollutants. Only the entrained air/vapor and minor impurities remain when the fuel finally reaches the fuel pump. While the fuel is flowing through the fuel filter under positive pressure, any remaining particle impurities are collected and held. Air and vapor that were entrained are also separated and added back to the tank. Your engine then receives the clean fuel at the proper pressures. Each kit contains every piece of plumbing, hardware, wiring, mounting hardware, and other installation-related items.
