PROBLEM TO BE SOLVED: To restrain generation of vibration to prevent generation of abnormal sound by fixing a cylindrical damping member elastically deformable to a flow inlet of fuel of each socket in a communication pipe, sealing both ends of each damping member, and communicating the inside of the damping member with the inside of the communication pipe through the provision of a damping narrow hole penetrating a wall surface thereof. SOLUTION: In a fuel delivery pipe 20, a fuel lead-in pipe 2 is fixed to a side of a communication pipe 21 via a connector 5, and a socket 3 is mounted to a bottom surface of the pipe 21. The number of the sockets corresponds to the number of cylinders of an engine. A damping pipe 25 for absorbing pulsation pressure of fuel is mounted to a fuel flow inlet 13 of each socket 3 in the pipe 21 and the axis thereof may be substantially in parallel with the axis of the communication pipe 21. Each of the pipes 25 is arranged along the front and rear of the inlet 13, with both ends thereof being sealed with caps 25a, 25b. At the lower end of a portion extending to the right and left of each pipe 25, a damping narrow hole 26 is bored to cause the inside of the pipe 25 communicate with the inside of the pipe 21.
