Not sure why some cars are more subject to vapor lock than others. It was surprsing on the '55 Clipper Super. My '53 Hudson has the problem even with the lines insulated; but the electric pump way back at the tank clears it up. My '54 Kaiser had it big time EVEN with the electric pump working full time until I rerouted the fuel line well away from the exhaust manifold. I drove another '54 Kaiser home today from an engine shop about 40 miles and it was ok until a mile from home. But fortunately it recovered. I have no electric pump on that car yet. But vapor lock is a fairly common thing. I never heard of it until 1994.
