At a boundary area between a high-pressure portion in which a discharge port of a fuel pump is disposed and a low-pressure portion in which an intake port is disposed, a pressure relief groove extending along the boundary area is formed so as to be communicated with the outside of the pump by means of pressure relief hole. Alternatively, a slit is formed communicated with the outside. Accordingly, a fuel at a high-pressure area portion can be drained with reliability. Further, by communicating the above pressure relief groove with a positioning pin insertion port, a single hole can serve both as a positioning pin insertion hole and a pressure relief hole.
