PUREFLOW® DIESEL SYSTEM
AirDog™ 
OVERVIEW 
The  PUREFLOW™  DIESEL  SYSTEM  AirDog™  Air/Fuel  Separation  System  is  the 
“missing link” between the fuel tank and the engine for diesel powered equipment. 
The AirDog™ 
delivers clean fuel to the engine free of virtually all air/vapor and at a positive 
flow. Thus, allowing the engine “test cell” performance and efficiency, while in “real world” 
use. 
The AirDog™ FP-100 is suitable for all stock and slightly modified 5.9 Cummin's
®
 Diesels. 
Connecting the AirDog™ to the stock 3 /8" OD (outside diameter) fuel suction tube at the 
tank is OK. 
Satisfactory performance and operation from the AirDog™ depends upon proper 
installation and maintenance.
