Fuel pressure before regulator peaks at 65psi... and after is like 40psi.

Does it matter where you tap it?

What are the fuel pill sizes for a 125 and 150 after regulator and if some of you have them for before, I'd like to hear them too just to get an idea. Thanks. What causes an intake backfire? not enough fuel or too much fuel or what... like to put a hole in an intake manifold. Thanks.
