PROBLEM TO BE SOLVED: To provide a fuel-feeding system for cooling a pump controller and miniaturizing a canister. SOLUTION: A fuel pump 20 is housed in a fuel tank 10. The pump controller 30 feeds power to a pump body 22 according to engine operation state, so that the pump body 22 of the fuel pump discharges a fuel quantity necessary for the engine and controls the rotational frequency of the pump body 22. The canister 40 adsorbs vaporized fuel inside the fuel tank 10 by activated carbon housed in its interior. Piping 105 is connected to the canister 40, to introduce the atmosphere inside the canister 40. When a solenoid valve 106 is opened, the atmosphere is introduced inside the canister 40 from the piping 105. Since the piping 105 is in contact with the pump controller 30, the atmosphere introduced to the canister 40 by the piping 105 is heated by the pump controller 30 and the temperature of the canister 40 is increased by introducing the heated atmosphere.
