Repainted and relined original fuel tank and installed new petcocks but have developed a slight fuel leak around the bolts that attach the petcocks. Is there some type of sealer needed to fix this problem?

I've had good luck with copper washers on my XS2.

I make washers from the above thin fibrous material. Don't use any other steel washers or lock washers. An inexpensive one-hole punch makes a perfect M6 hole, then you can use scissors to cut a washer around the hole you punched.

Thank you all for the great advice. The old bolts had a recessed rubber washer incorporated in the contact side of the bolt head. The new petcocks came with a thin metal-fiber washer that just ain’t cutting the mustard.
