Airdog has always held a reputation for holding high standards of manufacture. Each component is made out of high-quality materials to ensure life-long functionality. This is reflected in a number of features of the Airdog II-4G DF-100 that make it stand out from the competition.
Airdog makes some of the quietest operating pumps thanks to the gerotor pump with dual flow. As it uses an intermediate pump shaft, the electric motor is secured from any potential contact with the fuel. A self-aligning motor does result in less maintenance and a better lifespan of the pump.
The Airdog II-4G DF-100 provides you with so much more than the stock lift pump. Not only is the Airdog lift pump a better option, but it also comes equipped with the WS100 water separator and FF100-2 fuel filter with a tolerance of 2 microns.
The final result is a steady flow of fuel without imperfections which can cause fuel injector issues among many possible complications. Do not settle for a mediocre option as you’ll highly appreciate the Airdog II-4G DF-100 every time you turn the key.
Carefully designed, Airdog II-4G DF-100 can be installed on a number of truck models and is expected to last for as long as the truck without the need for a replacement. This claim is backed by a limited lifetime warranty on production and materials.
Does the air dog 2 come with all the hoses and fitting necessary to install on my truck?
Yes! It will include everything needed for installation.
What AirDog pump do I need for my truck?
Original AirDog and AirDog II 100 units are recommended for up to 500 horsepower. Original AirDog 150 and AirDog II 165 units are recommended for horsepower up to 1000. AirDog ® II 200 units are recommended for anything that exceeds 1000 horsepower.
What kits will require dropping the tank or installing a suction tube?
All Original AirDog 150, AirDog II 200 Systems and AirDog II 165 Dodge Systems. Any truck that is equipped with an in tank fuel pump will require a suction tube or module upgrade kit. We recommend installing a sump.
What is the difference between Original AirDog and AirDog II 4G?
The AirDog II 4G aside from having the adjustable regulator, the pump and base assembly are designed differently internally. The pump assembly has a Dual Inlet design allowing more fuel to flow into the Gerotor, this allows the pump to increase volume without having to work any harder. The base on the AirDog II is also much different. Internally the fuel is redirected through passageways after being pressurized, this allows less fuel to be returned to the tank and more fuel to be held in the filters for a true “On Demand” system. An intermediate shaft was also incorporated to completely separate the electric motor from fuel path along with an additional two bearings to reduce drag and increase reliability and lifespan of the AirDog II 4G.
If I daily drive my stock truck will running an AirDog 150 or AirDog II 165 4G hurt anything?
No, it will not hurt anything. With the Original AirDog’s High Flow return all excessive fuel not being used by your truck will be returned to the tank. When running the AirDog II 4G the Demand flow only allows the pump to send what fuel is needed to the injection pump, and all other fuel is recirculated internally in the base returning it to the suction side of the pump.
