On my latest 4K mile road trip through the Southwest I was having apparent
vapor lock problems when the engine and fuel lines were heat-soaked; i.e.
after driving in hot weather, shutting down then restarting after 30min or
so. At startup, the engine would stumble a bit until I got moving and got
some air circulating. I'm thinking maybe a ceramic coating of the manifold
and downpipes might alleviate this problem. Also wondering--this is mostly a
pipe dream--what coating the entire exhaust system would do. I would think
at least it would lessen the heat under the driver.

I haven't had this problem until the last few years, which coincides with
the greater prevalence of alcohol-laced gasoline. I can't prove a
correlation, but if the vapor pressure of gasahol is lower than 'real' gas
then it could be the cause. We tried to find a station that pumped pure gas
for comparison, but east of CA--and in most of CA--the pumps all read
'Contains Ethanol.'
