A fuel supplying apparatus comprises a first circuit for measuring a flow quantity of fuel which passes through a fuel supplying hose, a single mode setting switch provided on the hose at a position in a vicinity of a nozzle, a second circuit for discriminating the state of the apparatus based on the existence of an output of the first circuit, and a third circuit for controlling the supply of fuel. The second circuit discriminates that the apparatus is set to a preset quantity supplying mode when the switch is manipulated in a state before a fuel supplying operation is started, and discriminates that the apparatus is set to an integral quantity supplying mode when the switch is manipulated in a state during the fuel supplying operation. The third circuit performs a control so that a fuel supplying quantity is preset responsive to a manipulation of the switch and a fuel supplying operation is performed with respect to the preset quantity when the apparatus is set to the preset quantity supplying mode, and an operation of supplying a minimum integral quantity of fuel which is greater than a quantity of supplied fuel at a point when the switch is manipulated is performed when the apparatus is set to the integral quantity supplying mode.
