Hi guys, I don't post often but need your help. My tank has peeled around/under the fuel cap for the 3rd time!!! Its a custom paint job with hand pin stripes. I'm NOT going to have it painted it again. I want to find either a trim ring or pop up gas cap to cover the peeling around fuel Inlet. Once I find a trim ring I will sand down the paint underneath before adhesive ring installation to stop vapors from peeling paint even farther. I was thinking the Harley Davidson pop up fuel cap might work? If anyone has one could they please provide overall diameter so I can see if it will cover the peeling spot in the tank?
