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.

Great buy for an extreme chewer
Size: Large
I received this several days ago for my pit husky mix she is an aggressive chewer and it is still holding up, it's not as big as I thought it would be but it is big enough to wear she will not choke on it or get it lodged in her mouth and she loves it she carries it around everywhere definitely a good buy for us and we'll be buying more

Best Bones for My big dogs
Right when I gave my dogs these Willie Bones they went to chewing and would not put them down! They are the type of dogs that tear up stuffed toys and balls easily. These are really tough though!

Great bone for all dogs!!
I loved this bone! See my use of past tense 😂 I am so sad I bought this for my very destructive yorkie/shitzhu mix and he loved it so much! He was so at peace with it. I am sad to say that after having it for about a week or two it disappeared. I never let my dog go outside with it and I have tore my house to PIECES in search of it. He really misses it, I think I miss it more for him I can only hope this company will be having more available in the near future. This is a great bone for all dogs in my opinion. I managed to get my friends to even buy one for their dogs and the of course are just as pleased. Well until we can purchase another I will leave a great review regardless. Thanks Willie Bones for saving me and my dog
