The 6.7 Powerstroke has proven itself as the most powerful engine planted in the engine bay of a Ford SuperDuty and some would argue that its also the best engine in any Ford (although most 7.3 fans will fight you on this)! The reasoning for some to claim that its the best engine is that while its incredibly powerful, it also has been incedibly reliable with very few known failure areas. That said, a common, and VERY costly failure is that of the CP4 injection pump that when it fails, it will typically take out the entire fuel system along with it. In most cases, this failure is from two reasons, inadequate fuel delivery that causes a lack of lubrication to the pump and debris coming through the fuel system. The good news? you can alleviate both of these issues by upgrading your Powerstroke with an AirDog Fuel System!

The AirDog II-5G is an all in one premium fuel pump and filtration system for your 2017-2022 Powerstroke 6.7L 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-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 60 psi at idle and 70 psi under load from factory for a stock application. The regulator is adjustible up to 75 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.

TOO SMALL
Size: Medium, Color: Blue
Nice socks, but they are way too small. Says they fit size 6 - 10. I kept 3 ( I wear size 8) and gave 3 to my daughter (size 8.5). We both agreed that they were just too small.
