[TR] TR4 Gas Cap Gasket

[Glenn Owen]

The gasket on the gas cap assembly of my 67 TR4A has hardened and leaks. This
is the red rubber gasket shown here:

With gas prices down, I finally filled up for the first time and found out
about this the hard way - not good for mileage or paint. I haven't found a
source for a replacement at the Big 3 (short of buying the entire assembly).
Does anybody know of a source for the gasket alone? Or a workaround?
Thanks,
Glenn
