ABSTRACT:
A fuel pressure relief valve is provided to minimize evaporative emissions due to fuel leakage through the fuel injectors. The fuel pressure relief valve is sealed during operation to prevent flow through the valve. When the automotive vehicle is not operating and the temperature has cooled, the valve unseals. Thereafter, temperature rises that would otherwise result in pressure buildup are prevented.
