FUEL DELIVERY PIPE

A fuel delivery pipe capable of reducing a pressure pulsation at the time of a fuel injection due to injection nozzles, preventing vibrations and noises at an underfloor pipe arrangement, and turning down a radiate sound from the fuel delivery pipe, wherein a flexible absorbing wall surface 10 formed on a wall surface of a fuel delivery body 1 is loosened due to internal pressure changes to render internal volume of the fuel delivery body 1 increasable, alpha L/ 2ROOT V determined by sonic speed alpha L of fuel flowing through the fuel delivery body 1 and the internal volume V of the fuel delivery body 1 is set as 20 x 10 (m • sec)
