One of the biggest killers to engines, horsepower, and reliability are poor fuel quality and inadequate fuel delivery. The AirDog 4G is designed to alleviate all of these issues. By delivering enhanced filtration and water separation, you can be assured that your injectors are only receiving clean fuel that is free of aeration which increases fuel atomization. Further, by delivering either 100 or 150 gallons per hour (GPH) of fuel, you will never leave your cylinders starved for fuel, from stock up to 500+ rear wheel horsepower!
AirDog 4G is designed to operate at flows and pressures beyond the maximum requirements of the engine. It receives fuel under vacuum from the fuel tank containing entrained air/vapor, particulate contaminates and unknown quantities of water.
The fuel passes through the water separator which removes the large particulate contaminates that could damage or jam the gear rotor fuel pump. The fuel, with only entrained air/vapor and tiny particulate contaminates remaining enters the fuel pump.
The fuel, now under positive pressure flow, enters the fuel filter. As the fuel passes through the filter media and the remaining particulate contaminates are caught and contained, the entrained air/vapor is also separated. Through the positive fuel air separation features of the patented AirDog 4G the separated air/vapor is discharged from the filter and back to the fuel tank through the Primary Air/Vapor Discharge Port.
The fuel passing through the filter media is now free of contaminates and power robbing air/vapor. At pressures and flows able to meet the needs of the engine, it exits the fuel filter through two passageways. First, the fuel for the engine passes into the fuel pickup tube and on to the engine. Then, the excess fuel not needed by the engine recycles internally through the pressure regulator back to the water separator.
Unsure of whether you need the Airdog 100 or the Airdog 150? - Put it this way...if your truck is stock, or moderately stock(up to 500hp) you want the 100. If you've added a 100hp tuner or larger(500hp+), you will want the 150. If you have any questions, give us a call

Good Stability, But Quality Could Improve
I bought this bathroom shelf on Amazon and overall, I’m fairly satisfied with the purchase. It is sturdy and holds my items securely without wobbling. The assembly process was straightforward and didn’t take much time. However, I did expect it to be a bit wider based on the pictures, so make sure to double-check the measurements before ordering. I also wish the overall quality of the materials was a little better, as some parts feel slightly less durable than I expected. That said, it still does the job well and serves its purpose. It’s not a bad purchase, especially if you’re looking for something functional and affordable.

Sturdy and good looking.

Great shelves. As you’d expect - and mounting is just fine if you pay attention and hit some studs. I’ve got my wife’s plants on these for over a year with no problems.

Great shelves
Size: 16.5 Inch, Color: Rustic Brown
I loved these for my room, they were easy to install and super versatile, I love how easy it was to assemble them and how functional they became once I was done setting them up. They fit perfectly next to each other and I love how my room looks nice since I don't like relying on bookshelves or anything of that category and rather have wall shelves. They are really stable and I love how they look, they are also really easy to clean since I spilled some baby powder from my last waxing session and they clean up pretty well. Overall, just know that these shelves are super stable, durable and versatile, I love how many things can fit on it if you know how to organize or don't have much stuff to put on them; it's all up to you and what you need them for, so I recommend them 10/10!

Great shelves! Had for years!
Size: 16.5 Inch, Color: Rustic Brown, Size: 16.5 Inch, Color: Rustic Brown
I love these shelves, I’ve had them set up both ways, as a floating shelf and the other way where you get some side support. I’ve had them for years, moved with them, and they continue to work great. I’ve had a lot on them too weight wise (I love books) and they don’t cave in the middle. Great shelves and easy to assemble (I’m a newbie with a drill). Great value for the money, durability is great, adjustable, and great for what you get!
