An adjustable one would be ideal.

Did you ever pull the fuel pumps?
I didn't catch how many miles were on the car but the 30psi at idle isn't right. Has that been rectified? If not and you've changed the fuel filter, I would look at the sock filter on both pumps. They may be plugged to the point that they'll look like they are being sucked in by pumps. In that case I would replace the pumps since they probably been overheating trying to get fuel out. I had problem with my fuel pump filter causing the secondaries to shut down due to lean O2.
