My experience with epoxy (specifically Marine Tex, a high-quality
filled epoxy fairly similar to JB Weld except that the hardener is a
fuming jelly that's mixed 1:5 instead of 1:1) is that after some
months exposed to gasoline vapors and probably some liquid gasoline
it became rubbery.  This was repairing a fuel tank vent fitting on Scamp.

However it still retained the bond and as the repair required very
little mechanical strength it remained usable.

Yours,
