About 1 1/8″ internal dimension. Threaded taps that size around?
It’s not a common size, 1 1/8 X 20, but taps are available.
Oltimer made his own thread repair tool for tanks by lathe cutting threads on a 1 1/8 shaft and then cutting a groove lengthwise to catch the chips.

Wow Jim, that’s a while ago, and I made it out of 245 high carbon steel on my lathe if others are interested in making one. Most Aluminum tank connections are made from 48/52, so I will never wear out my tap. I’ll post a pic up here in a couple of days for the usual visual connection. LOl
