Mark, Thanks for the reply. I have looked at the manual and parts fish and I have the replacement part in my hand. What may appear to be a snap ring is actually just the rubber seal that attaches to the bottom of the new reservoir. If there really is a snap ring, it sure is not shown. I will try to get a Honda mechanic to look at mine, and see if it should pop right off is what I think, but who knows. Have you taken one of these apart before? Thanks again. Tim C.
