What are the differences between and AirDog and AirDog II? -
The AirDog II aside from having the adjustable regulator, the pump and base assembly are designed different 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.
Airdog does not offer a CARB # for the system. The fuelsystem should not require a CARB (E.O.) number beings the item does not link with the vehicles emissions. If an item increases a vehicleâ€™s emission above factory specifications, itâ€™s considered illegal for use on public roads in states that have adopted the CARB emissions standard.
