Abstract: A fuel system for a vehicle includes a fuel tank configured to provide fuel to an engine of the vehicle, a shutoff valve configured to selectively restrict a flow of the fuel along a flow path between the fuel tank and the engine, a temperature sensor configured to monitor a temperature of at least one of the engine of the vehicle or a temperature associated with a body area of the vehicle and provide a temperature signal, and a controller coupled to the temperature sensor and the shutoff valve. The controller is configured to control the shutoff valve to restrict the flow of the fuel in response to the temperature signal indicating a temperature in excess of a temperature threshold.
