I've heard that the gravity fed fuel systems don't seem to experience the
vapor locking and I've never experienced carb ice in any vehicle but my VW.
I'd think a pressure system would be more immune than gravity fed.

I think If it sucks it's more immune but if it blows it's less.
That's why new cars have the pump in the tank. Unfortunately most
planes don't.
