The AirDog II-5G is an all in one premium fuel pump and filtration
system for your 1999-2003 7.3L 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-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 55-60
psi from the factory for a stock application. The regulator is adjustible up
to 70 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 from the fuel tank. 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.
