Abstract: A fuel system includes a fuel injector having an inlet conduit extending along an axis, a nozzle opening, and a valve needle which is moveable to selectively permit and prevent flow of fuel from the inlet conduit through the nozzle opening. The inlet conduit has a seal support flange which provides a seal support shoulder which is traverse to the axis. A fuel rail assembly includes a fuel rail having a main fuel passage which receives fuel from a fuel source and a socket having a socket bore extending thereinto from a socket open end such that the socket bore is in fluid communication with the main fuel passage and such that the inlet conduit is received within the socket. A sealing ring which is metallic circumferentially surrounds the inlet conduit within the socket bore such that the sealing ring is compressed between the socket bore and the inlet conduit.
