する燃料圧力調整装置。A fuel pressure regulator for a fuel-injected gasoline engine in which a pressure regulator is installed in the fuel passage from the fuel pump to the fuel injection valve to control the recirculation amount of surplus fuel using a diaphragm that operates based on the differential pressure between the engine intake negative pressure and the spring river. A solenoid valve that is controlled by a timer is installed in the negative pressure line leading to the air chamber of the pressure regulator so that it closes when the engine is stopped and opens after a predetermined time delay when the engine is restarted. A fuel pressure regulating device characterized in that a part of the negative pressure pipe connecting the air chambers of the regulator is arranged in a high ambient temperature area near the engine.
