Started logging fuel pressure

For over the last 10 years it has been electric pushing through a working mechanical. I went this way because I was chasing a stumble in the upper rpm’s and knew someone running the electric/mechanical setup successfully. Turn out to NOT be my issue, was collapsing a hyd lifter, but the system worked so it stayed and was forgotten. The sensor is in the line 5” from the carb inlet without anything else in between. The “stock” filter on the engine isn’t a filter. (There’s a big Canton filter back at the tank) The hard fuel line just goes straight through it. I want to be able to make sure I can put enough fuel in the bowl to handle Q16, just want to be able to bump the pressure/velocity if needed. I did do the free flow fuel into bucket test back when I was just running a blue pump. Checked out okay. Still nosed over above 4500-5000. Thought the cheap regulator might be the issue. Went solid lifter and the red with mechanical at the same time. Problem solved. This weekend should be able to swap to the black pump with an aeromotive deadhead SS regulator. Return style would be better, but will probably go to an in-tank deal at some point.
