ABSTRACT:
A fuel feeding pipe having a first feed oil pipe extending from an oil filler port, a second feed oil pipe projecting from a fuel tank, and a tightening belt for connecting and tightening these oil pipes together, comprising an outer fitting pipe provided to the first feed oil pipe, and an inner fitting portion provided to the second feed oil pipe having low-temperature resisting and ozone resisting seal rings fitted therearound. The fuel feeding pipe is formed in one body by fitting the outer pipe around the inner fitting portion having the seal rings, then tightening the tightening belt fitted over at least the engaged region of the outer fitting pipe and the inner fitting portion. The invention achieves the minimization of a fuel permeation, high hermeticity without influences from various environments, the promotion of efficiency of replacement operation, and the vibration and impact resisting connection of the pipes.
