It's held on with a large fender washer and a screw. Note how the parts are put together and in what order. I had to clean out the tube, clean off the washer and remove any small debris inside. I put everything back together, and all works well. My vacuum release valve rotted out, and you can't buy spare parts. I just work around it. Good Luck!
Thank you. That is just exactly the information that I was looking for!
Which is kind of ironic, because I went down today and carefully did the checks that Sunnie000 (post # 2) recommended. Everything seemed to be OK so far as I could tell, so I used it to change oil in the starboard engine and it worked like a charm. So obviously cockpit error on my part somewhere along the line. I still am glad to have your info for down the line, though. Thanks.
