ABSTRACT:
A fuel pressure control system has a fuel pressure regulator having a reference chamber and a fuel chamber separated by a diaphragm which opens and close a fuel return passage in accordance with a pressure difference between both chambers. There are provided an accumulator for containing an air pressurized by a supercharger, and a temperature sensor for sensing a temperature of the fuel. A control unit normally puts a three-way electromagnetic fuel pressure control valve in a first position to introduce an intake manifold vacuum into the reference chamber. When the temperature sensed by the temperature sensor is higher than a predetermined value, the control unit puts the valve in a second position to introduce a high pressure air in the accumulator into the reference chamber to prevent vapor lock by increasing the fuel pressure.
