Maybe we shouldn't get too fixed on the idea of "dissolving". There
can be no question that ethanol has a detrimental effect on perspex.

I'd be surprised to see Perspex used on a car fuel system. ;-)

My 1963 Mini had a short length of transparent plastic tubing leading
up to the carburettor (not perspex, but I can't remember the details).
Eventually it hardened and fractured.

Was very common on many engines in the 70s (particularly small engines
such as lawn-mowers) it is still sold as fuel pipe.

Except petrol in those days had very little benzene.

I'm intrigued at the plastic and the plasticiser in that pipe. Most
plasticisers are soluble in benzene for instance and you end up with a
hardened, non-flexible hose.
