10% ethanol boiling when stopped

Searching for experience.

A lot of the gas we purchased this summer was marked 10% ethanol at the
pump. When we stopped, it boiled over and smelled up the coach,
particularly bad at high altitudes. Restarts were also a bit of starter
grinding. No problem at sea level or cold weather.

I assume (that word) that the gas boiled off in both the carb and maybe
the feed lines. Caspro sells an in line fuel pump that would pressurize
the feed line that would prevent the line from boiling and would prefill
the carburetor for restarting. From experience, is this the corrective
solution or does more need to be done?

Our current limitation is that in the state of Californian, any change in
the system, including adding a fuel injection system is verboten . If
they spot a non standard change, they will not issue registration until
the system is returned back to the stock condition. It matters not that
the exhaust is better with fuel injection, they don't know what happens
off idle and unloaded conditions where the emission test are done so they
want everything stock.

My current plans are to go to some fuel injection system when the coach
hits the age of 30, in 2003. What temporary solution has proved
successful?
