Abstract: A fuel injector includes a nozzle body configured to be inserted into a fuel injector receiving bore of the internal combustion engine along a nozzle body axis; a valve housing held in fixed relationship to the nozzle body; and a first locating pin and a second locating pin each extending from the valve housing. The first locating pin extends from a first locating pin fixed end which is fixed to the valve housing to a first locating pin free end. The second locating pin extends from a second locating pin fixed end which is fixed to the valve housing to a second locating pin free end. The first locating pin and the second locating pin elastically deform when inserted into the bore, thereby preventing rotational movement of the fuel injector about the nozzle body axis.
