置。 A fuel pump control comprising a fuel pump provided in a fuel tank and having a motor section and a pump section rotationally driven by the motor section, and applied voltage control means for applying voltage to the motor section of the fuel pump. In the apparatus, a consumption amount detection means for detecting the consumption amount of the fuel supplied to the fuel tank, and a consumption amount for determining whether the fuel consumption amount has reached a predetermined amount based on a signal from the consumption amount detection means. Until the determination means determines that the amount of fuel consumed has reached a predetermined amount, the voltage applied from the applied voltage control means to the motor section of the fuel pump is controlled by a predetermined voltage. 1. A fuel pump control device comprising: means for reducing applied voltage.
