Abstract
A fuel supply line system for a fuel injection nozzle which is inserted into the cylinder head of an internal combustion engine, having a pressure connector that communicates tightly on the inlet side with the connection piece of an inlet tube and on the outlet side is pressed axially, via a sealing face, against a seat face on the nozzle holder body of the fuel injection nozzle by means of a screw connection. A shoulder is formed on the pressure connector, when the pressure connector is screwed into a threaded bore, in order to absorb the tightening moment, the shoulder is pressed against a contact pressure face embodied complimentary to the shoulder on the nozzle holder body and extending annularly all the way around, and that the sealing face is disposed on a body that is provided between the pressure connector and the nozzle holder body and is deformable in a defined way by the screwing in of the pressure connector.
