PROBLEM TO BE SOLVED: To feed fuel to the engine to the last drop even when a tractor provided with fuel tanks on right and left sides swings to the right and the left. SOLUTION: In the working vehicle, a plate-like check valve 23 is provided near the center in the right and left direction of a communication pipe 22, and fuel is fed only from one of the right and left fuel tanks 21R, 21L toward the other. A fuel pick-up pipe 24 is branched from a side of the communication pipe 22, to which the fuel is fed from the check valves 23, so as to feed the fuel to the fuel pump. A fuel return pipe 25 is branched from a side of the communication pipe 22, to which the fuel does not flow from the check valve 23, so as to return the fuel returned from the fuel pump to the communication pipe 22 via the fuel return pipe 25.
