PROBLEM TO BE SOLVED: To provide an evaporation fuel processing device capable of making an adsorber exhibit desorption performance sufficiently as compared with conventional devices.SOLUTION: When it is determined that the internal temperature Tc of a canister having a heat transfer surface formed so as to guide fuel flowing in a fuel tank during the operation of a fuel pump is lower than a predetermined temperature To (step S1), an ECU determines whether the driving voltage of a fuel pump is a high driving voltage (step S2), controls an FPC so as to raise the driving voltage of the fuel pump (steps S3, S5) when determining that the driving voltage of the fuel pump is not a high driving voltage, and thereby increases a current flowing to the fuel pump so as to heat discharge fuel. |
