To provide a fuel pump module having a high degree of freedom in arrangement of other parts in an upper part of a bracket for sealing an opening of a fuel tank even in the case of providing a tank internal pressure sensor for detecting the pressure inside the fuel tank.
In this pump module, a sensor unit 42 having a semiconductor diaphragm is provided in a recessed part 22b of the bracket 22 having a flange part 22a for holding a fuel pump 14 through a high-pressure filter 18. This recessed part 22b is sealed by a sensor cap 48 provided with a pipe-like lead-in tube 48d to compose a tank internal pressure sensor 48. The internal pressure inside the fuel tank 10 is led through an inner pressure lead-in tube 42a, and on the other hand, the atmospheric pressure is led through an open air lead-in opening 48a provided in a lead-in tube 48d to detect the pressure inside the fuel tank 10.
