Received BMW PN: 61 67 8 252 743 from eBay seller partscontainer
Finalized my headlight washer head replacement and filled washer reservoir 1/2 full.
The o-rings seem to collapse on these things after a decade or so. That wasn't the problem with my original part, it appeared to be leaking from the metal ball in the base of the part.
So far no leaks with the new part!
