Abstract
Tabs and slots are provided on a fuel injector and a fuel rail respectively to provide for the injector to be installed in a transverse through-hole in the fuel rail by circumferentially registering the tabs with the slots, inserting the injector into the through-hole to a predetermined depth, and then twisting the injector about its own axis to remove the tabs from their insertion registry with the slots and cause the injector to become axially captured in the through-hole by the tabs being axially captured within circumferential extensions of the slots that are cooperatively axially defined by a shoulder in the through-hole and an overhang.
