Abstract
A fuel supply line, which serves to supply fuel to a fuel injection system for internal combustion engines. The fuel supply line includes receptacles, in each of which a stepped receiving bore is formed with the bores arranged to surround the injection valve in the axial direction and open both at the mouthpiece and the connection end of the injection valve. The injection valve is held by a holding body with a holding shoulder of the injection valve resting on a holding step of the receiving bore. The receiving bore of the receptacle extends outside the flowthrough cross section of the fuel supply line. A filter element is provided in the flow path of the fuel between the flowthrough cross section and fuel openings at the circumference of the injection valve. The fuel supply line, together with the receptacles, is advantageously manufactured of plastic as an extruded part.
