Why GM opted to not include a factory fuel lift pump on all of the early model Duramax's is still a mystery. While the CP3 injection pump is able to draw adequate fuel pressure at stock power levels, anything above that its been proven that fuel pressure quickly begins to drop off, limiting the amount of overall power that can be achieved, as well as decreasing potential fuel economy, and potentially harming the injection pump and injectors due to a lack of lubrication.
The AirDog II-5G is an all in one premium fuel pump and filtration system for your 2001-2010 Duramax diesel. This system removes water, particulates, and entrained air from the diesel fuel. The entrained air that is separated from the fuel is returned to the tank through a small return fitting. The fuel is delivered to the engine at the correct pressure and flow rate to meet the demands of the engine under all operating conditions.
The AirDogII-5G DF-165 systems feature a built in adjustible diaphragm pressure regulator. All AirDog II-5G systems include a complete installation kit. The AirDog II-5G, for this particular application, is preset at 8-10 psi from factory for a stock application. The regulator is adjustible up to 55 psi for fine tuning the system to perfectly match up to your current and future performance upgrades.
HOW IT WORKS:
The AirDog II-5G DF-165 draws fuel from the fuel tank through a 5/8” suction line to reduce the risk of cavitation at the pump. The fuel is then drawn through the water separator where 92% of water is removed per SAE spec 1488. It is then pressurized through a Gerotor pump and sent to the 2 micron fuel filter before it is sent to the injection pump. The air from aerated fuel, due to tank sloshing and engine return lines, is separated and sent back to the tank through the 3/8” return fitting. The excess fuel that the engine does not use is recirculated through the diaphragm regulator back to the suction side of the pump.

Single greatest thing I’ve ever bought for my dogs
Color: Charcoal, Size: 35" x 23"x 3.5", Color: Charcoal, Size: 35" x 23"x 3.5"
Few years ago we got our dog a dog. It was a bad idea. Our first dog is incredibly smart. He’d much rather hang out with humans, sitting in his own chair at the table while we play board games and chat than chase a ball. He uses talking buttons and picked it up quickly. Even as a little puppy he was kind of serious and when we’d take him to the dog park he’d mostly just run around barking at other dogs who were having too much fun.
Then came his brother who turned out to be the absolute opposite in every way. A silly, goofy, snuggly, floppy little muppet of a dog. Highly empathetic and Looooves to make people laugh. Our other dog mostly wanted nothing to do with him, barely tolerating him at the best of times. We thought, surely he’ll learn to love his brother. But 3 years later… nope.
Our first dog loves a good pillow so I thought this might make a good gift. I had no idea just HOW good. For some reason ever since our dog opened this gift he’s been obsessed. But so has our other dog. We initially were worried it would become one more thing for them to fight over BUT we were wrong. The dogs have been getting a long SO well! As long as it’s on this pillow, our first dog allows our second dog to come close enough to touch him.
They sleep next to each other, they wrestle, there’s no growling or grumping and our first dog will come over and lay next to his brother if he’s laying on this.
We’ve started calling it The Peace Pillow.
Anyway, I could have just said “it’s great” but it might actually be magic. Your experience may vary.

Super soft, cozy, and great quality Dog Bed
Size: Small 24"x18", Color: White, Size: Small 24"x18", Color: White
This pet mat exceeded my expectations. The material is incredibly soft and plush, and you can tell right away that it’s made with comfort in mind. My pet laid on it immediately, which is always the best sign. It provides just the right amount of cushioning without being too thick or heavy.
The quality is excellent — the stitching feels sturdy, the fabric doesn’t shed, and it holds its shape well with regular use. It’s lightweight and easy to move around, making it perfect for use in crates, on the floor, or even on furniture for extra protection. Cleaning is simple, and it still looks great after use.
Overall, this mat offers great durability, ease of use, and excellent value for money. It’s stylish, practical, and extremely comfortable for pets. I would absolutely recommend this to anyone looking for a cozy, high-quality mat for their dog or cat 🐾

Cushion for the pooch’n
Size: Small 24"x18", Color: Brown
I’ve been using the ULIGOTA Dog Bed Crate Pad Plush Soft Crate Bed in my dog’s crate for daily resting and overnight sleep.
Right out of the package, it’s clearly designed for comfort first. The plush top feels soft and inviting, and it immediately makes the crate look more like a cozy sleeping space rather than a hard plastic tray. Once fluffed up, it provides a decent layer of cushioning that’s noticeably more comfortable than a bare crate floor or thin mat.
In terms of fit, it sits well inside standard crate sizes and doesn’t bunch up too badly once settled. The anti-slip bottom helps keep it in place during normal movement, which is especially helpful for dogs that reposition a lot while sleeping.
Comfort-wise, it works well for small to medium dogs that just need light padding. It’s warm and soft enough for everyday use, and most dogs seem to settle into it quickly. However, it’s not a high-density or orthopedic-style bed, so it doesn’t offer much support for dogs that need joint relief or extra structure.
Durability is average. It holds up fine under normal sleeping use, but it’s not ideal for heavy chewers or dogs that dig aggressively. Like most plush crate pads, it’s more of a comfort layer than a rugged long-term solution.
Pros: very soft plush surface, comfortable for everyday crate use, easy fit in standard crates, non-slip backing helps stability
Cons: not chew-resistant, limited support for heavier or senior dogs, cushioning is on the thinner side
Overall: a solid, budget-friendly crate pad that improves comfort and warmth significantly over a bare crate, but best suited for calm sleepers rather than heavy chewers or dogs needing orthopedic support.

Soft dog bed perfect for small breeds
Size: Medium 30"x20", Color: White
This dog bed is very soft and fit perfectly in my dogs crate. I like that it came vacuum sealed and was really easy to open and leave out to expand. The material is durable and it is perfect thickness for a small breed dog. My Maltese puppy loves it and has been sleeping so well on it, she is very comfortable. The material is durable and easily washable, I already had to run it through the washing machine. Well worth the price and easy to fit in a crate or small space.
