Beginning with the 2005 model years, Dodge opted to move the diesel lift pump from being mounted in the engine bay to inside of the fuel tank basket to help avoid the lift pump failures that had plagued them since 1998.5 model years. Overall, it was a positive move on their part as failures were reduced, but it was also quickly determined that especially for those looking to increase the horsepower of their trucks, even a little bit, this pump was completely inadequate. And to make matters worse, this new positioning of the pump inside of the fuel tank made upgrading that much more difficult. Fortunately, AirDog has a complete system that includes all of the components you'll need to make sure you'll never have to worry about fuel pressure again!
The AirDog II-5G is an all in one premium fuel pump and filtration system for your 2005-2018 Cummins 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 17 psi from the factory for a stock application. The regulator is adjustible up to 55 PSI so you can fine tune the system to perfectly match up to your current and future performance upgrades.
HOW IT WORKS:
The AirDog II-5G DF-165 draws fuel 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.

Great wallet
Color: Steven Medium Brown, Size: One Size
Great and very durable wallet. They are slim, fit well in a pocket, and are thin, unless you have lots of CC and money in it.

Slim and elegant, beautiful leather
Color: Derrick Brown, Size: One Size
I bought this wallet for my son for his 36th birthday. I love that it is a true Fossil wallet and all that goes with anything that is a Fossil product. Style, masculine elegance, beautiful soft grain leather, and the Fossil logo embedded on the front, right bottom of the billfold. It came in different colors but I chose the soft brown one. This is also very sleek, has plenty of compartments for ID, cash, credit and business cards, and it is RFID blocked. I didn't realize when I purchased this that it is to be worn in the front pocket of the pant. It is a fashion made for men who don't appreciate a wallet in the back. It can be very uncomfortable and someone can easily lift the wallet out of the back pocket...So Fossil is producing this item to wear in the front for easy access and protection. It is small but no less accommodating. I showed it to one of my other son's and he wished I'd get one for him, and he is very fashion-forward, but practical. So I'm very pleased with my purchase although I haven't heard from the birthday boy yet! Also it came in the usual Fossil tin box that all their products are housed in-original with a bit of funk, perfect for any aged man.
