The AirDog II-5G A7SPBC262 DF-100-5G Air/Fuel Separation System is the next generation in fuel delivery systems for your 2015-2016 GM 6.6L Duramax LML (Stock To Moderate).

The wiring harness is now 12-gauge from the battery all the way to the internal connections in the motor. A Metri-Pack 280 connector replaces the Dutch 2-pin connector which allows more current flow without creating excessive heat. All other connectors in the harness are weather packs to keep the elements out. This system has the same 4G motor technology that has proven itself to be a reliable, quiet operating system. It also retains the "Demand Flow" of the older Air Dog I variants. Demand Flow means whatever fuel the injection system does not use gets recirculated back through the filter base.

The AirDog II-5G offers protection and performance like no other lift pump. Their patented air separation, along with a water separator, and fuel filter makes sure the expensive components in your fuel injection system get all the clean fuel they can handle. The AirDog II-5G also overcomes loss of power due to driving in higher altitudes with a factory fuel pump. By eliminating spray pattern disruption due to air entering the system, this system helps to improve overall engine performance. This allows the engine to keep its designed injection timing which allows a more complete burn of the fuel entering the cylinder. This increases engine efficiency across the power and torque range.

The AirDog II-5G is the first diesel Fuel Air Separation System to include an integrated diaphragm fuel pressure regulator. This regulator offers better fuel flow at pressure, allows for more fuel pressure adjustability, and can even be boost compensated. In addition, all 5G systems come with upgraded wiring harnesses and connectors.
