Garage stench after parking car - does non-ethanol help?

[ckessel]

Several years ago on a fuel vapor lock/boiling discussion here, one of the Cal gents mentioned that the then current pump fuel 2016?, had a boiling point of 150*. Think about that. What do you imagine the underhood temps are, along with coolant temp/airflow etc, when it's running and then shut off? And the ethanol added fuel seem to generate quite a bit more vapor due to that than non.

The fuel does seem to boil easily here, it causes hot start issues with my Ranchero and with my old Vette before I swapped it to EFI. So far the Coronet seems ok probably due to a lot of air flow compared to the other cars.
