The AirDog II-5G A7SABC510 DF-165-5G Air/Fuel Separation System from GAP is the newest generation of fuel delivery systems for your 2011-2014 GM 6.6L Duramax LML (Moderate To Extreme).
The AirDog II-5G is the first diesel Fuel Air Separation System to include an integrated diaphragm fuel pressure regulator. This regulator allows for more fuel pressure adjustability, offers better fuel flow at pressure, and can be boost compensated. This system features 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 AirDog II 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. This also helps overcome any loss of power due to driving, especially in higher altitudes with a factory fuel pump. Furthermore, this system improves engine performance by eliminating spray pattern disruption due to air entering the system. This allows the engine to keep its designed injection timing which allows a more complete burn of the fuel entering the cylinder. This increases overall engine efficiency across the power and torque range.
All 5G systems also come with upgraded wiring harnesses and connectors. The wiring harness features 12-gauge wire from the battery all the way to the internal connections in the motor. A Metri-Pack 280 connector replaces the Deutch 2-pin connector which allows more current flow without creating excessive heat. All other connectors in the harness use weather packs, to help keep the elements out.

Good sock

Great cushion and solid fit. Some days my feet are tired from the compression fit, but they do support my feet well.
