Q: What kits will require dropping the tank or installing a suction tube?

All 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.

Q: What is the difference FRRP ®100 and FRRP ® 150?

The Factory Replacement Raptor ® Pump is a direct replacement for VP44 Dodge pick-up trucks (1998.5-2002). All FRRP ® lift pumps use some OEM parts. The FRRP100 supports up to 500 horsepower, provides flow rates of 100gph and includes new fittings and fuel line from the lift pump to the injection pump.
FRRP150 supports up to 800 HP with the big line kit and fittings to provide a higher volume of fuel to the injection pump.

Q: What is the difference between the AirDog ® 100 and AirDog ® 150?

Physically there are no differences. The units are the exact same size. The AirDog ® 100 is a 2000 r.p.m. motor and has a flow rate of 100 gallons. The AirDog ® 150 uses a 3000 r.p.m. motor and has a flow rate of 150 gallons per hour. Also, depending on the application, the actual installation on the vehicle will differ as well. For Dodge trucks with an in-tank fuel pump, both the 100 and 150 systems will require you to drop the tank and install a suction tube.

Q: What is the difference between and AirDog ® and AirDog ® II 4G?

The AirDog ® II 4G aside from having the adjustable regulator, the pump and base assemebly 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. 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.

Q: 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.

Q: I have a Ford truck that I have put a Cummins engine in. What kit do I need?

With all unique truck builds. It is possible to need a miscellaneous part or two. When picking one of our products to fit your truck. You will need to get the kit that fits the engine for what you are running.
