The 6.4L Powerstroke was Fords first go at utilizing a common rail fuel system, compared to their previous HEUI systems found earlier trucks. With this change in fueling, Ford was able to get impressive power numbers in stock form, but it was quickly realized that by merely adding a good programmer, you could easily add another couple hundred horsepower. But, can this new factory fuel system support this kind of power? No, definitely not. The good news is for these kinds of power gains, the only thing you'll need to add to the truck is a good aftermarket lift pump, such as this 5G unit from AirDog.
The AirDog II-5G is an all in one premium fuel pump and filtration system for your 2008-2010 6.4L Powerstroke 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 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 10 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-100 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.
