Abstract

The invention relates to a fuel injection system, in particular a common rail injection system, in which fuel is conducted from a distributor pipe via high-pressure lines to injectors, by means of which the fuel can be injected during an injection cycle with a number of injection pulses, wherein each of the high-pressure lines is provided with at least one damping device for damping pressure pulsations. In order to simplify the production of the damping device, the damping device has a pipe, in which a core that is held at a distance via spacers so as to form an annular gap is provided.
