Abstract:
A fuel pump module comprising:a bracket for closing an opening of a vehicle fuel tank; a fuel pump held in the bracket, for sending out fuel stored in the fuel tank; and a tank internal-pressure sensor including: a diaphragm disposed in an inside of the fuel tank viewed from a principal surface of the bracket, for receiving internal pressure and external pressure of the fuel tank; a housing portion for housing the diaphragm; an external pressure lead-in portion having smaller section area than the housing portion, the external lead-in portion for leading the external pressure of the fuel tank into the tank internal-pressure sensor; and a lead-in hole defined in the bracket, for leading one of the external and internal pressures of the fuel tank, wherein the tank internal-pressure sensor detects the internal pressure of the fuel tank on the basis of an output of the diaphragm.
