Why GM opted not to include a factory fuel lift pump on all of the early model Duramax is still a mystery. While the CP3 injection pump can draw adequate fuel pressure at stock power levels (barely!), anything above that has 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 AirDog II-5G DF-220 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 the 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.
HOW IT WORKS:
The AirDog II-5G DF-220 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 Gearotor 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.

Super tough & Great squeak!
Pattern Name: Chipmunk
This Zippy Paws chipmunk is perfect for a small to mid-size dog. Our cocker and mini-poodle are hard on theirs and it holds together when other toys are in shreds within a few minutes. We have purchased several over the years.

Annoying sound but DOGGY TOY JOY!!
Pattern Name: Skunk
My 14 month old is squeaker OBSESSED, but she easily does surgery and defluffs. However this toy has been perfect. The sound when you shake is over the top and creates so much excitement. She loves to chase and chew this and play tug with this, and no tears from tug or points where she's tried to excise squeaker so far!

Great toy loved by 3 big dogs
Pattern Name: Skunk
We have a black lab and 2 grandpups (a Great Dane and a Cane Corso) that visit regularly. All 3 love this toy. All 3 destroy toys pretty quickly, sometimes within minutes. I have no idea what it is about this one, but they have not even remotely destroyed it except for major slobber damage from being so loved. I bought the first one months ago from TJ Maxx and then bought another on here thinking it could be a replacement when the first one got destroyed. The first one has yet to be destroyed. It sounds like there is a water bottle inside of it but it is some kind of coil thing. That being said, this toy can be very annoying to listen to, but we tolerate it for 3 very happy dogs.

Not for us, unfortunately.
Pattern Name: Chipmunk
Cute idea. We have doxies. Unfortunately, they ripped the apart in 5 minutes to get to the squeaker. I'm sure other breeds are more gentle with their toys. It would be a great toy for them.
