Abstract
In a fuel management system, shutoff means in a fuel supply line (12) closes when the pressure at a port (28) on the shutoff means exceeds some predetermined level. A most selector valve (42) attached to the port (28) connects to two electrically and mechanically independent shutdown valves (50, 52). Actuating either valve (50, 52) pressurizes the port (28), closing the shutoff means and stopping all flow through the supply line (12).
