Abstract
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.
