Thank you for the explanation! I "hotwired" the fuel pump in my old 3000GT like you've mentioned with the thicker wire directly to the pump. I'll keep the fuel controller and FPR in mind for when I move beyond stock power and stress the fuel system more.

I added the optional 0-90 fuel level sender to my Boyd tank, so I'll make sure to flip that around to 90-0. I found a few posts about this on the forum and it sounded like the easiest way to have an accurate fuel gauge. No adding resistors to manipulate the sensor readings, no fuel gauge that never reads full, no guessing when the car is actually near empty.
