Abstract
A fuel supply apparatus able to stop actuating of a fuel supply pump when the fuel supply is stopped or becomes slow, includes a control section which calculates an amount of the fuel in the fuel tank based upon a signal from a fuel gauge, and outputs the result to a fuel meter. The control section also calculates from the fuel gauge signal the amount of the fuel supplied into the fuel tank per unit of time, and if the amount of the fuel supplied per unit of time is determined to be less than a set supply rate, the fuel supply pump is stopped so that a malfunction of the fuel supply can be detected without mounting a special fuel supply sensor.
