My brother struggled for years with vapor lock. He tried everything to fix it: carb heat shield, heat sleeves for the fuel line, upgrading the cooling system, etc. He also has an electric fuel pump. None of it helped. What finally made the issue go away was using ethanol free gasoline. Presto, problem solved.
