kind of....i am pretty sure i know the answer, but looking for confirmation. i cracked the plastic ring on the tip of the injector when removing it. the crack runs top to bottom (as in the red line in the attached picture). the ring is still in place, but i am pretty sure that i should not put this injector back in and should replace it with a new one....

i'm looking for confirmation.....

thanks
