Abstract
A fuel supply system for supplying fuel from a fuel source to an internal combustion engine includes a valve assembly having a shut-off valve automatically responsive to negative pressures transmitted from an engine. The shutoff valve is diaphragm responsive and moves in the same direction as the flow of fuel in order close the valve assembly, thereby retaining the content of a fuel receptacle infinitely. The shutoff valve is adapted to withstand pressures which may develop in a fuel receptacle without opening.
