Yes, T at the carb inlet & run the line from the T to the reg "in" then run either reg "out" port to the tank & cap the other "out" port so you are in series regulating the return line only. You want to keep the psi not over 5.5 psi right at the carb with a known good gauge (they are notoriously inaccurate) & not less than several psi at WOT & the side bennie is the problem at hand & the contant return flow keeps the pump happy even if deadheading ain't the issue the constant flow will prolong its life. EDIT It acted badly with the mech and the elec seperately, & that is puzzling as I feel I am missing something especially since your fuel delivery requirements ain't that high & it was acting up with just the mechanical pump which takes the (elec pump) cavitation/deadhead/pump height out of the picture which would lead me to believe that the issue might not be in the front/rear delievery path. Just had an idea, is the crossover functioning & the intake getting real hot & there's NO pinholes in the front to rear lines?

try loosening the gas cap, just to be sure an incorrect cap, or tank venting issue is not causing a vacuum on the tank that stops fuel from flowing. This creates a lean condition that makes underhood temps rocket before the engine finally quits from no fuel. Quick easy test. This problem would show up in hot or cold weather, but would be worse with extra heat added.
