Bad FPR?

What are the symptoms of a bad or deteriorating Fuel Pressure Regulator. I'm having a fuel delivery problem with my 1985 turbo. Something is causing my main pump to buzz loudly and this results in a roughish idle. the car boosts and runs great, just the rough idle and loud pump.
The pump is brand new and I don't want to ruin it. New fuel filter too. All new plugs, wires, AIC valve, cap & rotor. Replaced all 4mm vac lines.
Could the FPR be malfunctioning? Theres no gas in the vacuum line and it seems to hold a vacuum when sucking on the line. If it passes these two crude tests, could it still be bad/going bad/sticking ???
Thanks,
Chris
