if you're using ethanol based fuel it does have a lower boiling point than traditional fuel. An electric pump out back helps as well as trying to get the lines and carb isolated from heat sources as much as possible. Especially if the line runs past the intake heat crossover. old tale says wooden clothes pins work but never tried them
Don't know about the thermal wraps but I'm a bit sketchy on them. I've requested data ( temp measurements) from several suppliers with no response
