PROBLEM TO BE SOLVED: To detect the abnormality of a canister without deteriorating emission, in a structure including a plurality of canisters. SOLUTION: In a fuel supply system 800, the communication between a first canister 812 and a second canister 817 is provided through an evaporated fuel transfer passage 820. A transfer control valve 821 is disposed in the evaporated fuel transfer passage 820, and the mutual communication between the first and the second canisters are provided when the transfer control valve 821 is opened. A first suction pump 816 and a second suction pump 819 are disposed in a first atmosphere open passage 815 and a second atmosphere open passage 818 respectively. ECU 100 moves the evaporated fuel adsorbed in one of the canisters to another canister and isolates the same through the cooperative control of the transfer control valve 821 and the suction pump corresponding to another canister when the abnormality detection of one of the canister is executed.
