A Warning About Pressurized Fuel Tanks -  These motors use pressurized fuel tanks.  Rather than sucking fuel from the tank, the dual line hose pumps air into the tank, pressurizing it to 4-7 PSI which forces fuel back to the motor.  Basically, these pressurized tanks are an extremely dangerous fire or explosion danger.  CLICK HERE to learn more about these tanks and how to convert to the newer and safer fuel tanks.
