AirDog Original AirDog for Dodge Cummins

Horsepower and what AirDog systems will support.
The compact AirDog® provides the most effective technology designed specifically for diesel pickups to remove water, particulates, vapor and entrained air from diesel fuel. The AirDog® replaces the Cummins factory lift pump and filter system. Your High Performance Dodge Cummins engine demands higher fuel flows. Yet, higher fuel flows increase the vacuum at the fuel pump and agitation in the fuel tank. These factors generate additional air/vapor in the fuel system preventing your engine from producing maximum power and efficiency.

Reliability and Performance! Two powerful reasons to add an AirDog® to your diesel pickup! The AirDog® provides the proper pressure/flow of fuel to your diesel engine under virtually all operating conditions for PEAK EFFICIENCY with CONSISTENT and MAXIMUM POWER OUTPUT!

The AirDog® eliminates the air in the fuel that robs your engine of consistently greater performance and can also cause permanent damage to your injectors. The AirDog® also provides the fuel pressures and flows your diesel engine needs to produce maximum power, any time, every time!

The physics behind AirDog® technology:
Diesel fuel contains varying degrees of entrained air in the form of foam on the surface or suspended in the bulk fluid as tiny bubbles. Additionally, fuel is driven into the fuel pump by atmospheric pressure, which is usually only enough pressure flow to fill the pump at idle speeds. Consequently, at higher operating RPM's , the stock pump cavitates producing vapor.

Air and vapor are compressible. The presence of air/vapor in the fuel injector delays the pressure build-up. This delays the injection, resulting in Retarded Injection Timing.

Retarded injection timing in a diesel, just like bad spark plugs in a gasoline engine, causes lost power, poor fuel mileage, and an increase in exhaust emissions. Retarded Injection Timing caused by air/vapor is the primary source of the rough idle, lost power, increased fuel consumption and excessive exhaust emissions of the diesel engine.

Air/vapor in the injector can also cause permanent damage in the form of galling and pitting of the barrel/plunger assembly and tip erosion.

The conventional vacuum feed fuel supply system does nothing to remove entrained air from the fuel. In fact, it only makes things worse. As the filter plugs with use, the already inadequate fuel flow to the engine is further reduced, increasing cavitation and retarding injection timing even more.

AirDog FAQ
What kits will require dropping the tank or installing a suction tube?
All AirDog® 150 & AirDog® II 200 Systems

Any truck that is equipped with an in tank fuel pump will require a suction tube or module upgrade kit.

What pump do I need for my truck?
AirDog® and AirDog® II 100 units are recommended for up to 500 horsepower.

AirDog® 150 and AirDog® II 165 units are recommended for horsepower up to 800.

AirDog® II 200 units are recommended for anything that exceeds 800 horsepower.

I daily drive my truck and it is only 300 horsepower. Will running an AirDog® 150 or AirDog® II 165 hurt anything?
No it will not hurt the pump. But it could cause you headaches down the road. Running way too much fuel to an injection pump that can't handle it can cause an increase in fuel pressure, which on some trucks could cause damage to that injection pump and possibly cause it to fail. Running a pump to fit your horsepower is suggested and will help keep you away from small potential issues.

What is the difference between the AirDog® 100 and AirDog® 150?
Physically there are not differences. The pumps are the exact same size. The AirDog® 100 motor is a 2000 r.p.m. motor and the AirDog® 150 motor is a 3000 r.p.m. motor. The differences between the two are as described. The AirDog® 100 is a 100 g.p.h. pump. The AirDog® 150 is a 150 g.p.h. pump. Depending on the application, the installation kits will differ as well.

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. Example: 2005 Ford with a Cummins out of a 2001 Dodge. You will need a kit for a 2001 Dodge.
