System for automatically changing fuel passages

Image Number 6 for United States Patent #7404388.

The present invention provides a system which can automatically switch passages of a fuel supply line and a fuel return line when the pressure in a fuel return line becomes higher than a predetermined pressure. Even when the fuel supply and return lines are incorrectly connected, the present system can prevent the problem of damage to a fuel supply system and fuel leakage which may be caused by an increased fuel pressure.
