Mechanical fuel pumps

I'm at work, now. My dyno sheets have the fuel usage, I'm checking them tonite...just can't remember right now, BUT are you saying if I'm making 576HP with no signs of fuel starvation(lean) clear to 6800RPM, I'm OK. Even though PRESSURE drops to 4.1PSI?

Oh. 3/8 pickup with 6AN line.

I do NOT want to go electric. Too many issues!
