After having 3 gas caps with bad seals, I started looking for new ones. Rummaging around my workshop I discovered some cork gasket material left over from a long range fuel tank install I did on a couple of Shorts aircraft. So about 15 minutes later I have 6 gaskets. I fit one on my tank in the basment, works great. We'll see how it does on the tank with fuel.
Gas cap gasket.

after re-reading nearly all the gas cap threads on the forum, I'd like to share a tip that worked for me.
I had done the whole gasket thing, gas cap spring etc
then I eyeballed the cap as it was closing and saw one side
contacted the tank lip way before the other.
A simple twist of the gasket and its retainer
(to ensure full contact all the way around on closure)
has eliminated any more leakage from a sloshing full tank.
Thanks to whomever pointed this out.

I settled on cork for a few reasons. It was free, it was on hand, and it has been working well on the aircraft for many years. All the rubber gas cap gaskets in my fleet are cracked. The one on my yamaha lasted 3 months. The cork I have is specifically for fuel aplications. It came from a race car vendor. I'm not too worried about bits falling in, the tank screens will get them, plus cork floats. I used a pen a scisors and a utility knive.

Oh cool island hoppers. If ya think I give a pensive sense to others piloting a motorcycle, you should of seen the passengers tense up when a pilot handed me the controls of one of these while he caught up on rest flying over swallow ocean below. I remember cork under coke bottle caps, gas can caps, fishing pole handles and desk blotters, usually chipped and cracked.

I do know that glued on cork is pretty tough, when the Real Thing CokaCola used to have contests with stuff under the cork in caps a fella stabbed him self to death in Fla when he slipped....
Life vests back in the olden days were hunks of cork canvas covered.
