PROBLEM TO BE SOLVED: To provide an oil feed pipe for a fuel tank which can smoothly feed oil. SOLUTION: The oil feed pipe 2 with one end thereof connected to the fuel tank 1 and with an oil feed gun insertion part 4 provided on the other end thereof has a double pipe structure comprising a small diameter pipe 5 of the diameter substantially as large as that of the oil feed gun 3 and a large diameter pipe 2a to surround the small diameter pipe so as to form a flow passage 6 to allow the fuel overflowing from the small diameter pipe to flow as the oil is fed between the small diameter pipe and the large diameter pipe. The high flow rate of the fuel in the small diameter pipe can be kept when the fuel is fed, and the fuel in the entire fuel pipes can be sucked into the fuel tank by the merging with the fuel which overflows from the small diameter pipe and flows in the flow passage between the small diameter pipe and the large diameter pipe at an open end part on the tank side of the small diameter pipe. Oil can be smoothly fed by this suction effect. COPYRIGHT: (C)2003,JPO
