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-100 systems feature a built in adjustable 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 adjustable up to 55 psi for fine tuning the system to perfectly match up to your current and future performance upgrades.

My dog loves glowing fetch at night!
Style: Glow Balls (Pack of 3), Size: 2.5 inch
Fantastic. Sturdy. My dog loves them
Glow in the dark is great for fetch at night. I keep a flashlight with me because the glow doesn't last really long. But they charge very quickly and are really bright.

Indestructible
Style: Fetch Balls (Pack of 2), Size: 3 inch
These balls are indestructible! We have a lab and a lab mix and they CANNOT damage these balls. They love them for fetch and to just chew on them (slightly squishy, but NO damage). Best toys we have bought for them.

Great trial set. Just be careful throwing the orange one!
Style: Assorted Balls (Pack of 3), Size: 2.5 inch
Blue isn't that easy to see in the yard
White charges with bright light/UV and is truly a game changer for night-time fetch. Both dogs clearly favor it.
Orange is easy to see in the grass at day
They're 3 different weights as well, so double trial. I prefer medium for my big dogs, though light performs well too
The orange is HEAVY and unyielding. Do NOT throw it with a ball thrower. It could damage your house or knock your dog out. Seems tough though.
