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.

Great for price ⭐
Size: Small, Color: Blue-2 Pieces, Size: Small, Color: Blue-2 Pieces
Bought this for my son's junior prom and it looked so good on him. I had to get a few alterations done because it was a bit too big for him but all in all great quality for the price.

Excellent Suit for the Money. Great, rich details.
Size: X-Large, Color: Black
This is a stunning piece of clothing. The material for the vests and pants are so luxurious and make it look like you spent a lot of money. Great versatility and thick material of great quality. The material is made of a rich fabric that feels subtle and gentle, but with the patterns showing well. It fits well and allows for movement. Whether you are looking for a wedding suit, or something to wear to a gala or bow-tie event, this is it.

Buy the suit. Be sure to measure!
Size: Large, Color: Red, Size: Large, Color: Red
Suit looks better than the photo in person. The suit is also made well. Great fabric and pattern!
My son is 6'1 and weighs around 135-140 pounds. I ordered a size large for him so the pants would be long enough. The pants were a little big but it was nothing a belt could not fix. The jacket and vest fit well too. The item also arrived on time.
***Suit runs small BUT if you take out time to do the measurements you will get the correct size.***
