That's true. I live in Atlanta and drive my truck all the time for work in 90+ degree weather, in rush hour traffic, stop and go, etc. and have never had a vapor lock, high heat problem. All stock engine, carb, fuel pump, steel lines, etc.

Steel dissipates heat better than rubber anyway. Insulating the lines means that if and when they do get hot, they will stay hot.
