Upgrade the fuel system on your 2015-2016 GM 6.6L Duramax LML (Stock To Moderate) with the AirDog A4SPBC190 FP-100-4G Air/Fuel Separation System from GAP.
AirDog has engineered this system to remove water, particulates, vapor, and entrained air from diesel fuel. This lift pump and filter system is what your vehicle needs to deliver clean fuel to your engine.
The AirDog operates by pulling fuel from the fuel tank containing entrained air/vapor, particulate contaminates and unknown quantities of moisture. Fuel passes through the water separator that removes water and large particulate contaminates. Next, the fuel with only entrained air/vapor and tiny particulate contaminates remaining, enters the fuel pump. Under positive pressure flow, the fuel passes through the fuel filter and the remaining particulate contaminates are caught and contained, the entrained air/vapor is also separated and returned to the tank. The clean fuel then flows at the proper pressures up to your engine. Each kit includes plumbing, hardware, wiring harness, mounting bracket, and all components needed for installation.
This AirDog system incorporates the 4G motor they have been using for years with excellent success together with their conventional nonadjustable/high flow return base. By keeping this fundamental layout, AirDog is able to provide a reasonably priced system with a well-proven and dependable motor design.
Your diesel engine needs better fuel flow when you upgrade its parts and performance. Vacuum at the fuel pump and agitation in the fuel tank are both increased by higher fuel flows. This causes more air/vapor to enter the fuel system and lowers the engine's performance. Injector barrel/plunger assembly galling, pitting, and tip erosion can also be brought on by air and vapor. The AirDog eliminates air from the fuel that might harm your injectors permanently and keep your engine from operating as it should. Additionally, the AirDog offers the fuel pressures and flows your diesel engine needs to operate at peak efficiency.

Great toy. Definitely worth it.
Pattern Name: Classic Squeaky Tug, Pattern Name: Classic Squeaky Tug
This is a great toy. I bought this for my dachshund, and it's still going strong after 2.5 years. The string part came off after a few months, but that's fine. This is always her go-to toy.

Perfect so far!
Pattern Name: Classic Squeaky Tug
My dog has a habit of tearing up toys in just a few minutes, so far, this toy has lasted a few days, the rope is already showing signs of wear.
I wish there was a way to attach a new rope when this one goes...
She is a mid-sized dog with a LOT of energy, and she's very destructive, digging, chewing on things she's not supposed to, etc.
This helps with that, she can play with it for a long time, we don't have to always 'check' to see if she is tearing something up.
She loves grabbing it by the rope and swinging it around the sides of her head, it doesn't hurt her, and she LOVES this toy. Out of ALL of the toys that we have bought her, and that she loved, THIS ONE has been top dog to her. We love watching her play with it, it also wears her out and she'll then take a nap, which is always good.
Oh yeah, the size if PERFECT for a mid-sized to a large dog, I'm not sure about any smaller dogs. She can squeak the squeaker on it fine too, but not at first, she had to 'find out' how to do it on her own.
As far as chewing it into little pieces like one person has said, I can't attest to that, and I hope that is not the case.
I will return if she does end up chewing it into pieces, because she in known far and wide for that! :)

Large adult aggressive chewer? No. Puppy? Yes
Pattern Name: Classic Squeaky Tug
My large adult dog who is an aggressive chewer got this toy in pieces within minutes, BUT this is a great toy for a lighter touched dog. When I got my newest addition (Malinois mix puppy. Pls thoughts and prayers for me), this toy came to mind because she loves chewing and she’s only 11 weeks old! She needed an interesting toy that is sturdy and won’t hurt her teeth or gums, but is still interesting (the rope piece and the squeaker). She’s not nearly as rough of a chewer as my older guy YET. But when she gets bigger, she will more than likely destroy this. She is almost 20lbs at 11 weeks right now, so I will update if she does destroy it.
Long story short:
Not good for large aggressive chewers, good for aggressive chewers on the smaller side (maybe 15-30lbs)
