I don't need a pressure regulator if I go mechanical? We have a mechanical on the 429 in the other hotrod and put a pressure regulator to make sure it didn't push higher than what the holley was supposed to be getting. of course I don't know how much it actually needed to restrict it.

thanks guys. stainless has to still be cheaper than braided, which was my original idea but uncle suggested not spending so much money and only using braided in the shorter runs.
