Then cut an X in the center with a sharp scraper and with my lefthanded tin snips spiraled outward until I was close to the right inside dimension. Then I glued the gasket on to the brass. And to finish I used a Dremel with a grind stone to smooth the edges and get the brass to the exact size of the gasket. To remove the burrs on the back I sanded with 150 grit sandpaper. The cap now turns much easier ( I'm sure the grease helps) with no sign of the gasket bunching up. That should finally finish this little adventure. All this just to keep the gas cap from walking away on its own.

That looks great. Hope it seals good.
