PURPOSE: A temperature reducer of returned fuel is provided to reduce the temperature of fuel inside a reservoir cup to become a high temperature by the returned fuel. CONSTITUTION: A return line(24) is connected with a chamber(25) in a fuel pump(21). The end of the return line is located in front of an outlet(26) of the chamber. A suction line(30) is connected with the chamber to inject fuel outside a reservoir cup(22). Cold fuel is injected to the suction line by using suction force to be generated in a gap when the fuel of the return line is discharged to the outlet of the chamber. Thereby, the output of an engine and the fuel efficiency are improved. Moreover, the production cost and the weight of a fuel tank are reduced.
