I uploaded a baseline video of the fuel pressure before the filters. I calculated 54sec for a 1 and a forth cup.

Vacuum accumulator is not connected to the fuel pressure regulator, just the location.
The vacuum line does go to the dizzy, I will check to see if there's a difference in feel between hot and cold.
I believe my fuel tank is vented correctly and wouldn't the baffles only work in turns? The fuel exit is towards the back of the tank, so a straight should force the fuel to the back of the tank. I am experiencing the issue straights and turns, plus AutoX is only turns.. and the first couples are flawless (not my driving, the engine) so I don' think it has to do with the baffles.
Here is the fuel pressure regulator around 100F
I guess the next step is too run a gopro inside the engine and see if the pressure falls when it gets hot.
