PURPOSE: A fuel pump module is provided to reduce noise caused by the residual fuel discharged through a regulator into a reservoir and improve the durability of a fuel pump module. CONSTITUTION: A fuel pump module comprises a flange assembly, a guide rod, a reservoir assembly, a fuel pump, and a regulator. The reservoir assembly is fixed to the guide rod and accommodates a fixed amount of fuel. The fuel pump is installed inside the reservoir assembly and supplies fuel to an engine. The regulator controls the pressure of the fuel pump in order to discharge the residual fuel into the reservoir assembly. The reservoir assembly comprises a hollow silencer(600) fixed to a discharge port.
