Tuning Street Demon carb

my stock-replacement mechanical pump with 5/16" lines can't supply enough fuel for a 450-hp 360
Should I upgrade the fuel supply before trying to tune the carb more?
I ran the 750 version on my stroker, in the 1/4 mile, with stock 5/16 line. At the time ran low 12’s @110ish no supply issues ever. Carter muscle pump, then a Carter electric (no regulator required version) simply because I wanted electric.
IMO, check all clean and Tune more.
