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.

Great Pillows
Style: Side Sleeper, Pattern Name: King
I was very skeptical about purchasing pillows online. After much research, I decided to buy two of the king size pillows. When they arrive, they were rolled up tightly in plastic. I fluffed them up and got new pillow cases for them. The first few days, I was tossing and turning. After giving them a few days, I can honestly say they are very nice pillows. Not to firm and not to soft...a very nice medium! They have a cool feeling when you lay on them. These pillows are great for those who sleep on their back AND side sleepers. No feathers have been poking out. My significant other LOVES these pillows. Been sleeping great and feel like I made a great decision getting these. Great value, great materials and great quality. I highly suggest trying these out if you're looking to replace your pillows.

Great quality but big
Style: Side Sleeper, Pattern Name: King
These pillows seem to be very good quality. I couldn’t wait to try them. I soon realized that they’re very thick & too high for my neck. I can push the pillow down but it doesn’t stay so I’d say they’re too firm for me & don’t support the neck properly because of the height.

my fav now after using 50+ pillows
Style: Back Sleeper, Pattern Name: King
I have always struggled to find the perfect pillow, and so far I have had 50+ pillows. Personally, I like my pillow to be on thinner side as I look for more support for my neck.
This is my first time buying pillows online, because I like to physically touch and feel the firmness and thickness before I purchase my pillows. I am so glad I did it! These pillows are just PERFECT for me! Perfect firmness, perfect thickness and perfect material.
One thing I suggest is that be extra cautious when you open the package. These pillows were rolled and put in a relatively thin shipping bag, so when you open with sharp objects be careful not to cut your new favorite pillows!
I let the pillows sit for about 48 hours before I started using them, but I assume you don't have to wait that long.
Overall, I am very happy with my first online pillow purchase with Serta!
