Figures 2 and 3 show that the pump module assembly portion 3 provided in the fuel pump body 1 includes a buffer portion 31 having two through holes formed in parallel, and two through holes of the buffer portion 31 can be positioned in the vertical direction. The outer yoke 32 of the ground fixing buffer portion 3 i is configured. The outer yoke 3 2 has a pair of holding portions extending on the side of the fuel pump body. The buffer portion 31 is sandwiched between the pair of holding portions of the outer yoke 3 2 to hold the buffer portion 31 to the outer yoke 3. 2. In Fig. 3, (a) is a front view of the pump module assembly portion 3, (b) is a bottom view of the pump module assembly portion, and (c) is a line X-X 'in (a) Sectional view. The two through holes of the buffer section 31 are located in the fuel pump body!
