Claims

[Scope of Claim for Utility Model Registration] (1) A mounting bracket that is provided hanging down inside the fuel tank, and a mounting bracket that is installed inside the fuel tank via the mounting bracket, and while sucking the fuel in the fuel tank from the suction port, Fuel temperature detection means for detecting the temperature of fuel in an in-tank fuel pump device comprising a fuel pump that discharges fuel to the outside from a discharge port, and a filter connected to a suction port of the fuel pump via a suction pipe. and pump reversal control means for rotating the fuel pump in reverse for a predetermined time based on the temperature detected by the fuel temperature detection means when the engine is stopped. (2) A vapor release valve according to claim (1), wherein a vapor release valve is provided in the middle of the suction pipe to cause vapor in the suction pipe to flow out when the fuel pump is reversed by the pump reversal control means. In-tank fuel pump device.
