Just reached 100 miles on my freshley rebuilt 318. Have not had any problems till I got home from work today. I pulled on to my street and the engine stumbled then shut off. So I pulled over and it started up with no problem. I have a fuel pressure gauge in line to the carb and it was reading 12psi. I have a Mr. Gasket electric pump from Auto Zone which is rated to 7 psi. Should I just get a pressure regulator? Any other advice would be appreciated.
