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.

Abstract: A fuel injector retention arrangement includes an interior space which extends into a fuel rail socket along an axis. A retention flange of a fuel injector extends radially outward therefrom such that the retention flange is disposed within the interior space. A slot extends radially from the interior space to a fuel rail socket exterior surface and a retention groove extends radially outward from the interior space. A retainer includes a first leg extending through the slot and a second leg extending through the slot, the first leg and the second leg being connected to each other at one end by a retainer base. A lobe of the first leg extends into the retention groove and supports the retention flange and a lobe of the second leg extends into the retention groove and supports the retention flange, thereby retaining the fuel injector to the fuel rail socket.
