OVERVIEW
Welcome to PureFlow
®
AirDog
®
Fuel Air Separation, Filtration and Delivery System for the Diesel Engine
The AirDog
®
II Fuel Preporator® is a premium fuel pump and complete filtration system for the
Duramax Diesel Engine. The system removes water, particulates, and entrained air from the
fuel. The entrained air separated from the fuel is returned to the tank through a small return
line. The fuel is then delivered to the engine at the correct pressure to meet the demands of
the engine under all operating conditions.
The AirDog®II-4G systems feature a built in adjustible pressure regulator. All AirDog®II
and AirDog®II-4G systems include a complete installation kit.
The AirDog®II-4G for this particular application are preset at 8-10psi from factory for a
stock application. The regulator is adjustible for fine tuning the system for performance
upgrades.
WARNING:
RUNNING THE PUMP ABOVE 75PSI FOR THE 100 AND 165 AND ABOVE
30PSI FOR THE 200 WILL DECREASE THE LIFE OF THE PUMP SIGNIFICANTLY AND MAY VOID THE
WARRANTY.
