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.

Highly Recommend!!!
I bought a second set of these toys for my puppy who is a Chorkie because he LOVES them! They're super durable, very bouncy, extremely light weight, soft and flexible. They're the same size as a golf ball so they're perfect for small dogs. I would highly recommend these especially if you have a puppy who likes to chew and play fetch.

Perfect size and very durable! Flexible but sturdy.
Perfect for my Frenchton puppy. Easy to pick up in her mouth and they are flexible but sturdy. Unfortunately lost all three already, lol, so guess I’ll be buying more. 🤦♀️

More like a cat toy size ball. Still a good toy.
I should have paid more attention to the size as they are slightly bigger than golf balls. The ones I was looking for are identical but about the size of a grapefruit. My dachshund has one and it is her favorite ball toy. That's on me though. These are more of a cat toy size ball. These do look like they are the same material as my pups larger one which is durable and fun for her to throw and bounce. The holes make it easy for the pups to grab and run quickly or catch in mid-air. I'm not sure how other small dogs would do but these are too small to play tug-of-war with my little girl and she is definitely not as interested in them as she is with her bigger one. I think we will donate these to animal control since I am sure they have some small dogs or cats that would appreciate these more than our picky girl lol. Still a great toy but just not the size she likes.

Nice, long lasting balls.
My dog is not an aggressive chewer and solely just wants to play fetch. As a small 8lbs dog, this is the perfect size for her. Typically these will dry rot after a few years of use. We do buy these so it’s a little bit less destructive while throwing a ball inside the house.
