<p>A purpose of the present invention is to provide a fuel delivery pipe having a flexible absorb wall surface formed on a wall surface thereof in which a fuel introduction pipe is connected to an interior of the fuel delivery pipe body at one end thereof in a longitudinal direction in order to achieve a suppression of a transfer of a first mode of a standing wave and a second mode of the standing wave and an enhanced placement layout and inexpensive cost. The fuel delivery pipe includes the flexible absorb wall surface formed on the wall surface thereof and injection nozzles, in which fuel introduction pipe 10 is connected to one end of fuel delivery pipe body 1 of a returnless type without a circuit returning to a fuel tank and is coupled with the fuel tank through an underfloor pipe arrangement. In the fuel delivery pipe, provided that an entire length of an interior of fuel delivery pipe body 1 in the longitudinal direction is 100, fuel introduction pipe 10 is inserted into fuel delivery pipe body 1 up to a position between 15 and 35 or a position between 65 and 85 with regard to the entire length and then securely connected to fuel delivery pipe body 1.</p> |
