Abstract: It has been determined that a fuel delivery system with a fuel supply line and electromagnetically actuatable fuel injection valves produce fuel oscillations during opening and closing of the fuel injection valves and therefore generates noise, which is transmitted into the passenger compartment of the vehicle and annoys the passengers. In order to damp this kind of noise, at least one elongated, hollow damping body is connected at right angles to the fuel supply line and has a closed end. The axial length of the hollow damping body corresponds to 11/2 times the wavelength of the fuel oscillation to be damped in the fuel supply line. The length of the at least one damping body can also correspond to 11/2 times the wavelength of the fuel oscillation to be damped in the fuel supply line, divided by 2 or by a multiple of 2. The fuel delivery system is particularly suited for mixture compressing internal combustion engines with externally supplied ignition.
