The AirDog II-5G A7SABC509 DF-165-5G Air/Fuel Separation System from GAP is the newest generation of fuel delivery systems for your 2001-2010 GM 6.6L Duramax LB7/LLY/LBZ/LMM (Moderate To Extreme).
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 your expensive fuel injection system components get all the clean fuel they can handle. This also helps overcome any loss of power due to driving in higher altitudes with a factory fuel pump. 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.
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 is the first diesel Fuel Air Separation System to include an integrated diaphragm fuel pressure regulator. This regulator better fuel flow at pressure, allows for more fuel pressure adjustability, and can also be boost compensated. This system retains the same 4G motor technology that has proven itself to be a reliable, quiet operating system. It also features 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.

My puppy likes these a lot
Size: 0.06 Ounce (Pack of 16)
I keep getting these because my puppy likes them and they are safe for her to chew. They don't break off into pieces that can hurt her. I have a "Premier Busy Buddy Bristle Bone" that unscrews on both ends. You just slip these on and give it to them and it will keep them busy for a long time. I have the small size, but they have larger ones for bigger dogs. They also have one that has a sort of ball in the middle that these little round chews slip onto also. It's a pretty good product and I'll keep getting them until she gets tired of them.

My dogs favorite treat.
Size: 0.06 Ounce (Pack of 16)
My dog loves these. He has tummy troubles and these do not seem to upset him. He’s never had diarrhea from eating these. The size is perfect. He’s a small dog and has no problem chewing these up.

Gave my dog diarhhea
Size: 0.06 Ounce (Pack of 16)
I love the design of these toys - keep my pooches busy for a good amount of time. However, these treats gave one of my babies diarrhea, possibly due to the sorbitol, a known laxative for dogs :( My dogs are both ~11lbs, and they would only get one disk at a time in their toys, and still one had loose stools. I know it's not the rawhide because he dosen't have trouble with regular rawhide, but these are so soft I can only assume they have too much of other ingredients inside.
Update: I just tried the dental disks and my boy that was sensitive to the regular refills has no issue with those. There's definitely an ingredient in these which he is sensitive to.
