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.

Works for foot psoraisis
Size: 2 pairs black L
Got these for work (service industry) to reduce issues with psoriasis and blisters while putting on 20k+ steps a day. Over time the wounds healed and I could work without so much pain. I now don't use them all the time like I used to, only when a new lesion or blister appears, too prevent a breakout. Tip: if you're not in full breakout, wear thick socks under these as a barrier to friction.

Work well but run small
Size: 1 pair black L
They do seem to run a bit small. I bought them for my bf but snagged them from him because I couldn’t resist! I’m about a W8/12 and they were just a little big but unlike others, I just put them on while sleeping and didn’t walk around with them. If you’re just planning on that, they did a great job at sloughing and moisturizing 😎

Good socks they work.
Size: 2 pairs black L
I normally wear size 13&half to 14 men's, and these fit me ok. They sit just below the ankle. They can get a little tight for me so you should look out for that if you are on the thicker side. But they work as advertised and help moisturize your feet. I recommend wearing them if you're going to just be hanging around home for a bit in one spot as they can be a little slippery to walk in if you go fast. Would not recommend going up and down stairs.
