The AirDog II-5G A7SABC513 DF-165-5G Air/Fuel Separation System from GAP is a state-of-the-art fuel delivery system for your 2015-2016 GM 6.6L Duramax LML (Moderate To Extreme).
All 5G systems also come with upgraded wiring harnesses and connectors. The wiring harness features 12-gauge wire from the battery all the way to the internal connections in the motor. A Metri-Pack 280 connector replaces the Deutch 2-pin connector which allows more current flow without creating excessive heat. All other connectors in the harness use weather packs, to help keep the elements out.
The AirDog II-5G offers protection and performance like no other lift pump. Their patented air separation, along with a water separator, and fuel filter makes sure the expensive components in your fuel injection system get all the clean fuel they can handle. This also helps overcome any loss of power due to driving, especially in higher altitudes with a factory fuel pump. Furthermore, this system improves engine performance by eliminating spray pattern disruption due to air entering the system. This allows the engine to keep its designed injection timing which allows a more complete burn of the fuel entering the cylinder. This increases overall engine efficiency across the power and torque range.
The AirDog II-5G is the first diesel Fuel Air Separation System to include an integrated diaphragm fuel pressure regulator. This regulator allows for more fuel pressure adjustability, offers better fuel flow at pressure, and can be boost compensated. This system features the same 4G motor technology that has proven itself to be a reliable, quiet operating system. It also retains the "Demand Flow" of the older AirDog II variants. Demand Flow means whatever fuel the injection system does not use gets recirculated back through the filter base.

This suit was perfect for prom. The fit was clean, the material looked high quality, and the texture gave it a unique look. Definitely worth it.

Award winning tuxedo!
Size: Large, Color: Baby Pink, Size: Large, Color: Baby Pink
Love this tuxedo suit! I’ve worn it a few times - to two different weddings and an Academy Awards viewing party, where I even won for best dressed. I get so many comments on it. The jacket and vest fit perfectly, however the pants are long and I had to hem them, but “stitch witchery” tape worked fine. The pants are also a little “stiff” - not a smooth fabric. But for occasional wear, it’s fine! The bow tie was sold separately.

Slim fit
Size: Large, Color: Brown
I recently purchased the brown slim-fit suit and am very impressed! For reference, I’m 6’2” and 222 lbs, and while I usually wear a size large, I went with an XL based on the fit advice and it was the perfect choice. This suit does run a bit small, so ordering a size up is definitely the way to go.
The slim fit is flattering and modern without being restrictive, and the rich brown color adds a unique and stylish touch to any occasion. The material feels high-quality, and the overall craftsmanship is excellent. If you're looking for a sharp, well-fitting suit, this one is a fantastic option—just be mindful of the sizing!

Good Decision !
Size: Large, Color: Dark Black, Size: Large, Color: Dark Black
Upon receiving the suit we were definitely skeptical because certain materials don't match the pictures. But Baby when we say this one came and showed up. It was great material , not cheap feeling if you get what Im saying. The pants, jacket and vest all came as it said it would. Nothing was missing! It came pressed and very wrinkle free so it was taking care of prior to shipping out. We got a Large for my son because of course he wanted a slimmer fit. But it did work out. He had enough room to comfortably be able to move. And for it truly was a steal for how much it costed. This literally felt like it was suppose to cost a few hundred , but it was so affordable.

"Showstopper Suit That Turned Heads All Night!”
Size: Medium, Color: Violet Purple, Size: Medium, Color: Violet Purple
I absolutely love this suit. We bought it specifically to match my son's girlfriend's prom dress, and it could not have been a more perfect choice. After she picked out her gown, I spent the entire Sunday searching for a suit that would complement it, and when I saw this one, I knew it was the one. The colors, the pattern, the style—it all came together perfectly.
When prom day came, my son looked so confident, handsome, and proud. He and his date looked stunning together, like they coordinated their outfits down to the smallest detail. You could tell they were a couple just by the way they complemented each other. He received nonstop compliments, not only at the prom send-off but even later that night when we went to Texas Roadhouse. People were turning their heads and praising the look. It was truly a moment.
This was hands down one of the best purchases I have ever made on Amazon. I do not usually write reviews, but this suit deserves the recognition. It was sleek, bold, well-fitted, and absolutely top tier. If you're considering this suit, do it. It is a total showstopper.
