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.

This is a must have!
Size: Upgrade Queen (2 Pack)
One of my favorite purchases! I love that you can take stuffing out as needed. My husband kept majority of his in because he likes a full pillow. I prefer a flatter, soft pillow so I took out probably half of the stuffing. We both love them!

Excellent pillow.
Size: Upgrade Queen (2 Pack)
Wow these pillows are fantastic!!! First off they are good quality and sized as described. I'm forced to sleep on my back since I use a cpap every night. They suggest taking some filling out for "back sleepers". But in my case, I am disabled, overweight, and the way I position myself on a pillow is probably unique. I have a little of my shoulders, head and neck on the pillow. I didn't have to remove any filling. It was pretty good at first and after about a few day/nights, everything settled in just perfectly. It's truly one the finest pillows I've owned to date. (Part of my disability is a very painful neck & muscle malady, my head leans far to the right. Basically feels like a crick in your neck that never goes away. It's called tortacollis or dystonia depending who you talk to.) Because of this, I have truly spent hundreds and hundreds of dollars on different types and styles of pillows. A very select few have worked out fairly well over time until I found this one. As I said in the beginning, this is an excellent pillow and a great value as well. Hopefully this will work as well or even better for others. I purchased a 2 pack this time, 1 for home and the other for our RV. Definitely buying. another 2 pack to keep for future replacements. Pillows simply don't last forever. They get funky in time. No matter how clean you try to stay with bedding and personal hygiene, it just happens eventually. Sweet dreams. :~)

Size: Upgrade Queen (2 Pack)
Incredibly thick and firm pillows. Not great for stomach or side sleepers. They alway end up on the floor cause we find them uncomfortable. Don’t recommend, practically unusable
