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.

Asurion worked as intended.
After three years, my monitor failed. Asurion paid to send it to a repair center. I didn't save the box the monitor came in, and paid $23 to have it packaged up. They kept me informed of the various steps, such as en route, arrived, testing, and repair started. They discovered it could not economically be repaired and refunded my purchase price. The entire process from me telling them it was broken until the refund took 5 days. I am well satisfied with the service.

Great value - functions well with fairly easy setup.
I found the setup to be fairly simple. It performs exactly as I hoped. I needed a printer, copier and scanner - it is a great value. I did have to do some research to complete the scanner setup - that could have been easier overall.

Office‑grade, solid, fast, and capable.
I didn’t just buy a different printer — I moved up a class.
Compared to my Canon PIXMA: I feel about the Epson WF 4834 the way someone feels when they finally replace a flimsy folding chair with an actual piece of furniture. The difference isn’t subtle — it’s structural.
Price is awesome. I’m getting my money’s worth and more. Solid machine. Super easy to install on my network. Wireless connection is great! I print from different rooms all the time. Print quality is outstanding, professional looking. Easy to use, period. So far, I’m not disappointed.

Great Value! Great Printer
THE ONLY reason I can't give it a five is because it is the only printer I have ever seen with two trays that you have to print one or the other. Aside from that, BEST Scanner App EVER! Easy!! Hardly ever jams and then only when I put too many in, rushing to finish. The quality is fantastic!
