Of course it's possible. On a hot day if the plane is flown and then
parked on the ramp with the cowling closed, the heat under the cowling
can be so intense that it can potentially vaporize the fuel in the fuel
lines forward of the firewall. If the engine is restarted shortly
afterwards it's possible to experience vapor lock. This problem will
be worse if higher vapor pressure fuel is used (such as winter blend
autogas).

The solution is surprisingly easy. During those short turn-around
always open the cowling immediately after the shutdown. That'll let
the heat escape and avoid the vapor lock.

I have heard a lot of arguments about vapor lock, but I do not understand
how vapor lock could ever be a problem in a Cessna 182.

With the high wing configuration, the carberator will always have a positive
fuel pressure due to hydrostaic pressure. How can vapor lock *EVER* happen
in a Skylane? As an engineer, I don't see it happening.

Now, on the other hand, if you have a low wing airplane with a fuel pump,
then vapor lock is a very real problem.

But vapor lock in a high wing carberated engine.... not possible.
