All good suggestions from all posts. I had simlar concerns with several of my past SPFs. One with 514 was the worst. Went to 1/2 inch fuel line, aluminum thin spacers under the carb, regulator and line off the block which fixed the concern. One car I did put a return line on which did keep the fuel moving throughout the system and keeping it cooler. That car had an Aero Automotive fuel pump and regulator also.
