ABSTRACT:
A fuel supplying apparatus comprises a switch for driving a pump in response to unhooking of a fuel supplying nozzle from an accommodating part, a circuit for driving the pump and carrying out a fuel supplying operation until a preset fuel supplying quantity or a preset amount of money is reached, where the preset fuel supplying quantity and the preset amount of money are preset before the preset fuel supplying operation is started, a circuit for driving the pump for a predetermined short time in response to accommodation of the fuel supplying nozzle in the accommodating part after completion of the preset fuel supplying operation, and a circuit for comparing a measured flow rate which is measured in the flowmeter and a predetermined flow rate when the pump is driven for the predetermined short time, and for prohibiting the pump from being driven in response to the unhooking of the fuel supplying nozzle from the accommodating part when the measured flow rate is greater than the predetermined flow rate, even when the switch operates.
