Stupid ethanol!!!
Unacceptable! More searching resulted in quite a few threads going way deep in o-ring specs. But, it was determined that the standard oil drain bolt o-ring is a viable alternative. So, without draining or dismantling my tank, I was able to replace the o-ring (with HD part #11105) using a paper clip and a pair of needle nose pliers. 20 minutes total. This is how I did it;
1) disconnect fuel line
2) remove faulty o-ring with the paper clip
3) oil new o-ring and insert into sending unit with pinkie
4) push o-ring into place with needle nose pliers
5) reconnect fuel line
An old handlebar mounted mirror and one of those headband flashlight things made it super easy to see what I was doing.
The pic shows the faulty o-ring and if you look close enough, you can see similar problems with the tiny o-ring in the end of the fuel line. It makes me wonder how long the other rubber components in the fuel system will last before they start leaking as well. Might be time for me to buy all new parts (i.e. injectors)?

Thanks for the reminder!!
Thankfully, one station near me is now selling 87 octane ethanol free. I'm going to use that in my small engines.
My quick connect had to be replaced at 23k, 10 years old. I owned it since it was 8 years old/2k miles, so I'm pretty sure it had never been disconnected, and probably was from prior ethanol exposure.

As a matter fact, now that I think about it, the newest bike I have ever ridden is my 95 Heritage Softail Classic.
I avoid ethanol in all three of my vehicles when I can, but that is not always possible.
