Your Opinions on My Fuel System?

The only other concerns are having the regulator as close to the carb as possible so it can react immediately to any drop in pressure, having the line to the regulator go to the core support and then turn back toward the regulator so the inertia of acceleration feeds the regulator instead of starving it, and have smaller hoses from the regulator to the carb than you have going to the regulator, again to help reduce to as close to zero as possible the reaction time it takes to get back to full pressure.
