Improve the fuel system on your 2001-2010 GM 6.6L Duramax LB7/LLY/LBZ/LMM (Stock To Moderate) with the AirDog A4SPBC185 FP-100-4G Air/Fuel Separation System from GAP.
When you upgrade the components and the performance of your diesel engine, it demands improved fuel flow. Higher fuel flows increase the vacuum at the fuel pump and agitation in the fuel tank. This results in additional air/vapor in the fuel system and prevents your engine from performing at its absolute best. In addition, air and vapor can cause galling and pitting of the injector barrel/plunger assembly and also tip erosion. The AirDog removes air in the fuel that could cause permanent damage to your injectors and prevents your engine from performing at the level it should. The AirDog also provides the fuel pressures and flow your diesel engine needs to reach its maximum level of performance.
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.
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.
This AirDog system features their traditional nonadjustable/ high flow return base but integrates the 4G motor they have been utilizing for years with great success. By maintaining this base design, it enables AirDog to offer a budget-friendly system, with a very proven and reliable motor design.

Great for Chewers!
Flavor Name: Chicken, Size: 7 inch (Pack of 1)
Purchased for my German Shepherd Pup a few months back and it’s still going strong! It is by far his favorite chew toy. It clearly lasts a long time. It’s a nice size with some weight to it. Good for them chewers!

Not for aggressive chewers
Flavor Name: Bacon, Size: 5.25 inch (Pack of 1)
This bone is noticeably softer than most chew toys I've bought. That may be a positive for some dogs, but my dog was able to break off fairly large pieces, which made me nervous. It might work well for light chewers, but I wouldn't recommend it for aggressive chewers.

Great for aggressive chewers
These are some of the strongest bones I've ever seen. I have aggressive chewers and my puppy loved this bone. She lays on the garage and goes to town on it, not making any marks or chards or breaks like we do often have to deal with. They are long lasting as she has been chewing on it for a month now - well worth the money.

Great chewy for my dogs
My 3 dogs love these already. I smeared peanut butter on one side and passed them out. My 2 that aren't crazy active or aggressive chewers enjoyed the PB, then were done for now. Energizer bunny dog has now claimed all 3 and is alternating which one she chews on. Great buy for keeping them, especially her occupied.
