Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

6.5 -7 in my opinion way to high. It's not pressure you want it's volume. 5PSI is plenty. You want the fuel going into the bowl like a garden hose flow not spraying in.
Sounds like the needle and seat needs replaced.
I need to mess with the regulator, I got a Holley deadhead regulator and I have the screw all the way out (lowest pressure) and it seems like it’s still above 6. The pump I have is a 5-9psi electric pump so I wouldn’t think it’s overpowering the regulator
