The substance we laughingly call "gasoline" seems nicely written up here: http://en.citizendium.org/wiki/Gasoline
The part of the article that rings a bell with me, relating to "geysering" of the Holley carb bowl vents is this:
I think the article is worth a read!

PS: I didn't try ethanol-free gasoline. At the time it was harder to find than it is now, but possibly it would have a higher initial boiling point which could help to suppress the geysering I experienced. No problems with EFI ..]
The part of the article that rings a bell with me, relating to "geysering" of the Holley carb bowl vents is this:
You can see that some boiling can take place at a temperature as low as 95 degrees Fahrenheit, probably due to the ethanol (from corn). A lot more boiling can take place well below the 395 degree final number, where it all boils away, probably due to the many different kinds of liquids blended together to make the final substance.has an initial boiling point at atmospheric pressure of about 35 °C (95 °F) and a final boiling point of about 200 °C (395 °F).
I think the article is worth a read!
