||The part in question is a short rubber tube, approx 4" long with a black plastic ring at one end. I'm 99% sure that it was removed while I was pulling the radiator for my 120k.
Why am I uncertain? Because I have a neighbor that likes to wander over and start running his mouth every time I'm working on my car, and I find it's at these times that I get distracted and screw s**t up. :-|
