First off, I can't speak to the effects of ethanol on plastic tanks with any authority because I am not a chemist.

But from how certain you are that it has no ill effect, I'm betting you are, so thanks for the info smart guy.

Second, it does make sense conceptually that ethanol in the main tank could cause swelling that could cause cracks in the weak points of the outer shell.
