<VV> Vapor lock

I'll leave the expansion of this comment to a fuel engineer but...

Re: No Vapor lock in a 100 degree parade (Hi Ron!)

Fuel volatility is constantly managed vs ambient temperatures.  As the 
seasons progress, refineries adjust the fuel to provide good vaporization for cold 
starts and proper hot-restarts while also considering percolation during hot 
soak (Carburetor issue).   It doesn't surprise me at all that Ron didn't have a 
problem at 100 degrees and the "Other Bob" had one in a snowstorm.  Ron 's car 
was likley filled with the appropriate fuel and Bob was using fuel that was 
calibrated to vaporize well at 20 degrees in a relatively sealed, 120 degree, 
engine compartment.

Personally, I've never experienced vapor lock on any car under any condition, 
but then I'm only half as old as some uh the guys on VV (I'm 51) hehehe
