FUEL FEED DEVICE AND FUEL PRESSURE REGULATOR

Mounted on the upper surface of the cover portion (3) of a fuel supplying apparatus (10) to be mounted to an opening portion (2a) of a fuel tank (2) is a fuel pressure regulator (20), which contains a fuel pressure detector portion (21) constituted by a diaphragm portion (21a) detecting a pressure of the fuel discharged from a fuel pump (4) and a current control portion (22) for analogue-controlling the current flowing through the fuel pump (4) by a signal from the fuel pressure detector portion (21), whereby the fuel pump (4) is set to pump an amount of the fuel corresponding to that required by the injector mounted to the engine, so that the current consumption of the fuel pump (4) is reduced and the operating noise is lowered.
