Upgrade the fuel system on your 2011-2014 GM 6.6L Duramax LML (Stock To Moderate) with the AirDog A4SPBC186 FP-100-4G Air/Fuel Separation System from GAP.
This AirDog system incorporates the 4G motor they have been using for years with excellent success together with their conventional nonadjustable/high flow return base. By keeping this fundamental layout, AirDog is able to provide a reasonably priced system with a well-proven and dependable motor design.
The AirDog operates by pulling fuel from the fuel tank containing entrained air/vapor, particulate contaminates and unknown quantities of moisture. Water and big particle contaminants are removed from the fuel when it travels through the water separator. The fuel then reaches the fuel pump with just the entrained air/vapor and minute contaminants still present. The residual particle contaminants are captured and trapped while the fuel flows through the fuel filter under positive pressure. The entrained air and vapor are also separated and returned to the tank. The clean fuel is then delivered to your engine at the correct pressures. Each kit comes with all the needed plumbing, hardware, wiring, mounting bracket, and other components needed for installation.
Your diesel engine needs better fuel flow when you upgrade its parts and performance. Vacuum at the fuel pump and agitation in the fuel tank are both increased by higher fuel flows. This causes more air/vapor to enter the fuel system and lowers the engine's performance. Injector barrel/plunger assembly galling, pitting, and tip erosion can also be brought on by air and vapor. The AirDog eliminates air from the fuel that might harm your injectors permanently and keep your engine from operating as it should. Additionally, the AirDog offers the fuel pressures and flows your diesel engine needs to operate at peak efficiency.
AirDog has engineered this system to remove water, particulates, vapor, and entrained air from diesel fuel. This lift pump and filter system is what your vehicle needs to deliver clean fuel to your engine.

Marginal Quality
Doesn't fit very well, baggy. Material feels cheap.

Comfy Hoodie
Size: Large, Color: Mg03- Splatter1
This brand makes some decent stuff.
This is a nice thinner hoodie with some stretchy materials and a cool splatter design.
Comfy and easy to move in/ use for active occasions or just for chillin. Very versatile.
Color doesn’t fade or hasn’t yet for me and I like the contrasting drawstrings.
Size is right on; I ordered a size up and there’s plenty of room for layering.
However if you put anything heavy in the front pocket, like a wallet, the material will give way and sag.

Buy it.
Size: Large, Color: Mg03- Ethnic
I dont leave many reviews, because life. However, this pullover deserves a review. Yes, it is big. Normally I would wear an XL but ordered a L based off sizing and reviews. The L is a hair big but I love the way it fits and its comfy.bthe color and quality is great. It is a little warm with the fleece lining, so it will be worn inside until fall, ir on cool summer evenings. I bought 2 and may buy more.
