The Pureflow AirDog II-5G A7SABC512 DF-220-5G Air/Fuel Separation System from GAP is the next generation in fuel delivery systems for your 2001-2010 GM 6.6L Duramax. The 5G is designed to be the longest lasting, most efficient, and quietest lift pump system GAP has to offer.
The AirDog II-5G utilizes a diaphragm style fuel pressure regulator allowing the pump to be boost referenced and adjusted from 7-70 PSI. The 5G Fuel/Air Separation System features a 4-bearing motor with an intermediate shaft that improves reliability and reduces pump noise. A demand flow design allows the pump to only send the necessary amount of fuel to the engine.
The dual feed motor supplies fuel to both sides of the gerotor pump to decrease air bubbles that cause cavitation. The 5G system features larger 3/4-16 O-ring boss inlet and outlet ports. A 7/16-20 (-4) low-flow return is used to prevent aeration in the fuel being sent to back to the tank. GAP is a proud authorized dealer of Pureflow Airdog products.

Nice boot!!
Size: 8.5, Color: Black
Very comfortable. Built well and obviously high quality. Fits a little big, about a size larger. They are a little thinner/cooler than the Danner Wildland and Haix Missoula. They do not have any NFPA rated tags or labels on the boot. Will upgrade the laces. Would love to see the boa system on this boot!

Needs work
Size: 12, Color: Black
I’m disappointed that I spent almost 400$ on a pair of boots and wore them for 3 days and both boot laces broke near the eyelets. As a wildland firefighter I need to be able to rely on my boots.

Like all Asics I've owned - Good
Size: 12 X-Wide, Color: Steel Grey/Cloud Grey
I've worn Asics for about 35 years now. Every pair I've had, and there have been many, have fit well and gotten the job done. The Gel-Venture 11 are performing as expected which is very well. The cushioning and support in the heel and arch are excellent. Very comfortable to walk and run in these shoes. Finally, and less importantly, the looks are just OK. The cheap "iron on" Asics logo doesn't look good. I've been purchasing Asics for as long as I have strictly for the performance quality anyway.

Nice, sturdy trail running and walking shoes
Size: 9.5, Color: Midnight/Grey Blue
I like Asics athletic shoes. They consistently fit my feet quite well. These shoes seem sturdy and have good grippy tread, ideal for light hiking, trail running and general every day use. Comfortable. My only gripe about Asics is the tread on previous shoes seems to wear out quickly. I walk and hike about 35-40 miles a week and the past Asics I’ve had usually lose their rear tread after six months so maybe that is normal.

Very comfortable
Size: 9.5, Color: Black/Cool Grey
Awesome shoe, very comfortable. As a trail shoe it is a little firmer than a running sneaker as expected. The unexpected was the comfort the shoe provided. Nice looking as well.
I've been wearing against most of my life. Always find myself coming back to them when I tried other brands.
Size consistency has always been near perfect.
