AirDog II Fuel Preporator

ADVANCING the AirDog® TRADITION with NEW and UNIQUE FEATURES! The AirDog II incorporates the demand flow. This means that it returns the smallest amount of fuel to the tank because most of it is recycled in the engine case itself. This small amount of fuel is taking the entrained air back to the tank rather than running to your engine.

Horsepower and what AirDog systems will support.
  • Stock - 500HP ---- FP-100 & DF-100
  • 500HP - 800HP ---- FP-150 & DF-165
  • 800+HP ---- DF-200

The AirDog II also has an adjustable fuel pressure regulator that you can set yourself for your application. Another feature is the high flow fuel module upgrade kit which eliminates the 1/4 tank issues associated with the Original AirDog application and most other fuel system setups. The return flushes back to the fuel basket or the fill neck to keep the fuel always supplied to the pump itself.

The patented AirDog® II system removes entrained air/vapor from diesel fuel which improves engine performance by:

  • Maintaining Correct Injection Timing
  • Eliminating Spray Pattern Disruption
  • Allowing for a Full Power Stroke and Complete Burn
Which leads to:
  • Increased Fuel Economy
  • Increased Power Output
  • Increased Torque Output
  • Longer Injector Life
  • Improved Throttle Response
  • Reduced Exhaust Emissions
  • Optimized Engine Performance
    AirDog® II also overcomes loss of power for diesel engines operating at higher altitudes.

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.
