I would definetly run an electric pump with the pump gas of today. I just run the Holley black pump dead headed and it works fine. But its even better with a return line as I may add one some day. So far I have been good but you have to watch the real hot 95 degree and better high humidity days so the gas wont boil in the carb bowls and then it loads up and stalls running real rich. The electric pump will help fight vapor lock also. Ron
