Summary Info:

Pureflow/AirDog II Fuel Preporator DF-165
Dodge 1989-1993 Cummins 5.9L

AirDog II is designed to operate at flows and pressures beyond the maximum requirements of the engine. It receives fuel under vacuum from the fuel tank containing entrained air/vapor, particulate contaminates and unknown quantities of water.

The fuel passes through the water separator which removes the large particulate contaminates that could damage or jam the gerotor fuel pump. The fuel, with only entrained air/vapor and tiny particulate contaminates remaining, then enters the fuel pump.

Product Description

Pureflow/Airdog 1989-1993 Dodge Cummins 5.9L AirDog II DF-165 Lift Pump Filtration System #A5SPBD340

AirDog II Fuel Air Separation System featuring Demand Flow Technology
AirDog II is designed to operate at flows and pressures beyond the maximum requirements of the engine. It receives fuel under vacuum from the fuel tank containing entrained air/vapor, particulate contaminates and unknown quantities of water.

The fuel passes through the water separator which removes the large particulate contaminates that could damage or jam the gerotor fuel pump. The fuel, with only entrained air/vapor and tiny particulate contaminates remaining, then enters the fuel pump.

The fuel, now under positive pressure flow, enters the fuel filter. As the fuel passes through the filter media and the remaining particulate contaminates are caught and contained, the entrained air/vapor is also separated. Through the positive fuel air separation features of the patented AirDog® II the separated air/vapor is discharged from the filter and back to the fuel tank through the Primary Air/Vapor Discharge Port.

The fuel passing through the filter media is now free of contaminates and power robbing air/vapor. At pressures and flows able to meet the needs of the engine, it exits the fuel filter through two passageways. First, the fuel for the engine, passes into the fuel pickup tube and on to the engine. Then, the excess fuel not needed by the engine recycles internally through the pressure regulator back to the water separator.


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.
