81 fuel cap gasket?

[CBXTed]

my fuel tank leaks when full at the cap. can you replace the gasket? I've seen replacement caps but I dont want to have a different key to open the tank...options?

You can buy a new fuel cap, buy a blank Honda key, cut one side of the key to fit your stock locks and ignition, cut the other side the key to fit the new fuel cap. Only one side of the key is needed to move the tumblers.
