I’m now going on 3 weeks with bike down because of an oring. You cannot find a size online or anything local that works.

This o-ring was not the same size as oem and did not fit my Sportster. It was larger in diameter and half as thick. I tried installing one and got it to fit but started leaking as soon as turned the tank over. This is not the correct size of the part number it replaces.
