Abstract: A fueling system is substantially composed of one or more fueling units, a liquidation managing machine, a first fueling state communicator, and a second fueling state communicator. The units contains a fuel sort discrimination unit for supplying fuel of which sort is consistent with fuel in a tank to be fueled, and a full-tank fueling unit for filling up the tank with fuel to a full-tank level. The liquidation managing machine settles accounts and controls signals input from the fueling units. The first fueling state communicator and the second fueling state communicator indicate fueling states of the fueling units, the first fueling state communicator functions by receiving signals from the liquidation managing machine, and the second fueling state communicator functions by receiving signals from the first fueling state communicator.
