According to the present device, tapping screws 4 are fitted from below through through holes formed in a pump module mounting portion 3 which comprises a cushion 31 and an outer yoke 32, and are brought into threaded engagement with a convex portion 22 of an upper bracket 2 and are fixed thereby. The outside diameter of a collar inserted between the tapping screw 4 and the through hole is smaller than the inside diameter of the through hole in the cushion 31 and the overall length of the collar 5 is larger than the length of the through hole in the cushion 31. The pump module mounting portion 3 is attached to the convex portion 22 of the upper bracket 2 in a state in which it is given degree of freedom in the vertical direction. With this construction, the present invention aims at providing a fuel pump module wherein, even in the case where the fuel pump is of such a type as delivers fuel by a vertical reciprocating motion of a plunger, vertical vibration of the body of the fuel pump which is generated with the reciprocating motion of the plunger can be prevented from being transmitted to the upper bracket through a holding mechanism.
