Abstract
A fuel injector includes a nozzle body to be inserted into a fuel injector receiving bore along a nozzle body axis; a valve housing; and a locating pin extending from the valve housing along a locating pin axis. The locating pin axis is eccentric to the nozzle body axis. The locating pin has a width in a first direction radially relative to the nozzle body axis and through the locating pin axis and a length in a second direction perpendicular to the width such that the width is less than the length. The locating pin includes a first crush rib and a second crush rib which are diametrically opposed at the length of the locating pin and such that the first crush rib and the second crush rib plastically deform when inserted into the locating bore, thereby preventing rotational movement of the fuel injector about the nozzle body axis.
