Abstract

A fuel supply line for use with fuel injection devices of internal combustion engines is proposed, having supports to contain fuel injection valves. The fuel supply line has an elastic wall section, with which is connected a rigid wall section and on which are fastened the supports. The elastic wall section is elastic to the extent that it damps the pressure pulsations of the fuel in the fuel supply line, whereas the rigid wall section assures the required rigidity of the fuel supply line.
