Maybe you can remove the line & fitting shown in the pic, reach in with a tool or bent bar and nudge the little bugger back out.
Annoying for sure, I've had a few old ones do that. They lay in the bottom of the end cap until I go in there and do a clean out. Likely the OD of the zinc has grown a bit larger with zinc corrosion products, making it tough to pull out.
Tough place to glue. I'd try JB Kwik Weld on end of a chopstick; its more viscous, less chance of running downhill and gluing the zinc into position. Let it set up a bit on the end of the stick first.
