PROBLEM TO BE SOLVED: To prevent voice guidance of a setter from being mixed with voice guidance uttered from the other speaker. SOLUTION: The fuel supply system 10 has a fuel supply machine body 24 with a fuel supply line, a pair of setters 26 which are provided on the front and back face of the fuel supply machine body 24 and set information on liquid feeding of the fuel supply line, a pair of speakers 60 which are provided on the front face (A side) and the back face (B side) of the fuel supply machine body 24 corresponding to the pair of setters 26 and a control circuit 36 having voice control means to control the voice guidance output from the pair of speakers 60. The control circuit 36 monitors voice guidance uttered from each of the pair of speakers 60 and when either one of the pair of speakers 60 (A side or B side) outputs voice guidance, the control circuit controls timing of voice information which is input into the other speaker 60 (B side or A side).
