摘要： A fuel supply system is provided with a static discharge circuit (30) placed on the surface of a cover (3) fitted in the opening (2a) of a fuel tank (2) and used to discharge the static electricity generated because of the intense friction between fuel and the filter element (5a) of a fuel filter (5) when the fuel passes through the filter element (5a). The static discharge circuit (30) is fitted with output terminals (38c) so arranged as to externally output an operation confirming signal for an operation confirming display lamp (37) by making use of a pulse signal at the time of charging-discharging. Therefore, the static electricity can surely be discharged and a decrease in the amount of fuel supply to and engine can also be recognized beforehand by detecting the fact that the filter element (5a) is clogged with foreign matter and/or the malfunctioning of a fuel pump (4) occurs.

摘要： A fuel supply apparatus having a fuel pressure regulator (60) for regulating the pressure of fuel discharged from a fuel pump (4) to a predetermined pressure, the fuel pressure regulator (60) including: a first chamber (62), formed in a case (61), into which fuel discharged from the fuel pump (4) flows, and a second chamber (63), into which the fuel flows via the first chamber (62); a fuel limiting means (64) disposed between the first chamber (62) and the second chamber (63), for limiting fuel flowing from the first chamber (62) into the second chamber (63); a pilot valve unit (65) having a passageway for opening to discharge fuel tank (2), when the fuel pressure in the second chamber (63) is more than a first set pressure (Pp); and a main valve unit (66) having a passageway for opening to discharge fuel into the fuel tank (2) when the fuel pressure in the first chamber (62) is equal to a second set pressure (Pm) between the first set pressure (Pp) and the predetermined pressure (Pi), whereby, in cases where returning flow volume drops, the pressure of the fuel delivered under pressure to the injector does not drop.
