<p>A fuel feeding pipe which is enables suppression of the pressure reduction of the fuel effectively while being used like an ordinary piping tube by adding a function to relax the reduction in the internal pressure to the tube itself and which can be arranged with a high degree of piping freedom and has a high reliability. The fuel feeding pipe is connected, when used, to a fuel rail for distributing the fuel to an injector and includes an outer tube (15) made of a flexible material and a bellows-shaped inner tube (16) housed coaxially in the outer tube (15) and forming a fuel passage therein. A sealed space (18) containing a liquid is formed between the outer tube (15) and the inner tube (16).</p> |
