The AirDog II-5G A7SABC509 DF-165-5G Air/Fuel Separation System from GAP is the newest generation of fuel delivery systems for your 2001-2010 GM 6.6L Duramax LB7/LLY/LBZ/LMM (Moderate To Extreme).
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 your expensive fuel injection system components get all the clean fuel they can handle. This also helps overcome any loss of power due to driving in higher altitudes with a factory fuel pump. 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.
The AirDog II-5G is the first diesel Fuel Air Separation System to include an integrated diaphragm fuel pressure regulator. This regulator better fuel flow at pressure, allows for more fuel pressure adjustability, and can also be boost compensated. This system retains the same 4G motor technology that has proven itself to be a reliable, quiet operating system. It also features 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.

⭐⭐⭐⭐⭐ "Excellent value for money and very efficient charging!" I bought this pack of 2 MagSafe chargers from TNDAJI and I couldn't be more satisfied. I love that it includes USB-C to USB-A adapters. This allows you to use them with both modern and traditional charging cubes, which is a great detail. The magnet adheres perfectly to my iPhone and does not release easily, allowing me to continue using the phone while charging. The blue light ring gives it a modern and elegant touch, in addition to helping to locate the charger easily in the dark without being annoying. The 15W works wonderfully. Charge my AirPods and phone quite fast for a wireless connection, and I haven't noticed excessive heating. For the price of an original one, you get two high-quality chargers with their adapters. Super recommended to have one in the office and another on the bedside table!"
