If I recall correctly, don't laugh, it does happen infrequently, some listers on
the Yam*h* XJ Owners Group had used some type of "modeler's latex" to repair
punctures in the flexible piston boots, with fairly good results.

Years ago, I found some vinyl repair glue that I used on some upholstery that is
still flexible to this day, although somewhat discolored. I can't vouch as to
whether it would be impervious to fuels, but would also be worth consideration.

I also have some "tacky glue" from Wally World's craft department that is
flexible when cured. Comes in a semi-clear squirt bottle. On larger tears, a
small section of nylon pantyhose may provide reinforcement.
