Abstract

PURPOSE:To allow respective fuel feed systems to be used in uniform frequency and promote efficiency in use and maintenance of the respective fuel feed systems, by detecting a car entry to a gas station, selecting an fuel feed system with low use frequency by a guidance control means and guiding the car to the selected fuel feed system by an information means. CONSTITUTION:When a car 6 comes into a site of a gas station 1 through an entrance 3, a car entry detector 5 detects an entry of the car 6 and generates a detection signal to a guidance control means 25. The guidance control means 25 selects from a fuel feed system condition table a fuel feed system to which the car is not yet guided. If a plurality of fuel feed systems are selected from the table, the fuel feed system with the minimum cumulative amount of fuel to be fed is determined by referring to a reckoning table. The guidance control means 25 transfers an output signal to a guidance lamp 14A provided at the upper part of a fuel feed device 9 and causes the guidance lamp to blink the car thereto. Use frequency of each fuel feed system is controlled on the basis of a cumulative amount of fuel fed therefrom and fuel feeding work is performed by using the fuel feed system with the minimum use frequency. Therefore, it is possible to eliminate fluctuation of the use frequency in the respective fuel feed systems.
