More importantly you should verify that the entire fuel system can handle
MOGAS. Wing/header fuel tank sealer, material used to bond bottom skin
to wing (and header to deck), fuel cap o-rings, drain o-rings, selector
seals (if used), gascolator and/or filter, non-teflon flexible fuel
lines, sight gauge lines (if any), header float switches (if
any), carb/throttle body, fuel transfer pumps, etc.
Vapor lock is more likely to occur firewall forward because of
heat. Else where it can occur from heat or altitude (reduced ambient
pressure).

Did someone use Mogas on Lancair 235 with
O235?
I asked Petersen and they can give me
an engine STC but they told me I should verify if the airframe is
compatible, expecially about vapor lock.
