The AirDog I-4G is the latest in fuel delivery for your 6.6L Duramax! Its patented design has been quality engineered to remove entrained air and water vapor from diesel fuel. The result is a compact, long lasting, efficient, and quiet fuel system made with superior quality.AirDog I-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 I-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 you want the 100. If you've added a 100hp programmer or larger, or even a modified lift pump, you will want the 150. If you have any questions, give us a call

Nice Side Table
Color: Ink Black, Number of Items: 1
This is a nice side table. The assembly hardware is of good quality. The wood product finishes are very nice and the pieces assemble solidly. The instructions are easy to follow except for the drawer slides where a little more concentration is needed . . . or maybe it’s just me.

Nice and sturdy side table but the white is not white
Color: Farmhouse White, Number of Items: 2, Color: Farmhouse White, Number of Items: 2
This is a nice-looking and sturdy side table. We found it easy to assemble. It works well in small spaces. Be sure to check the dimensions so you aren’t surprised by how narrow and long it is. The drawer is small, but big enough to hold some remotes or other small items. We ordered the white with brown top. Unfortunately, it definitely is not white but more of an ivory or cream color.

Great table!
Color: Espresso, Number of Items: 1, Color: Espresso, Number of Items: 1
Just what we were looking for! The table was well made and went together very easily (my husband and I did it in well under an hour). We were very pleased with the quality of the wood. The only thing I would suggest to the company is that the glide parts weren’t labeled with stickers like every other part was. That would have been a big help.

Some frustration, but overall worth it.
Color: Ink Black, Number of Items: 1, Color: Ink Black, Number of Items: 1
Sturdy. Everything came in one piece and the instructions were some of the clearest I've encountered for Amazon furniture. Took about an hour for me to muscle my way through with manual screwdrivers only. I do not recommend a drill unless you go slow, because screw placement will make or break this for you in my opinion.
Problems I encountered and how I overcame them:
Drawer was rickety, kept catching when trying to pull out. I had to go back and tighten the tiny black screws on the rails. If they are not as flush as you can possibly get them, they will cause the wheels to catch. Once I got them as tight as possible, the drawer pull out was much smoother.
Getting the first set of rails on. Space was EXTREMELY tight and frustrating. I ended up using a small screwdriver from my house, pressing it tightly with one hand, and using a pair of pliers to turn the screwdriver. Like a socket wrench type action. This sucked, I can't lie. And it wasn't possible to put them on earlier due to the cam bolts/screws under the rail. But I got through it.
Overall, this is worth the money as long as you are willing to take your time and line things up properly and really use some elbow grease to get the screws in straight and flush.
