In your experience on your car and others you have seen. Where was the fuel pressure regulator mounted? Mine is attached to firewall above brake booster with a solid mount and i can hear diaphragm opening and closing with a clicking noise inside car. In the engine bay you have to put your ear right up against it to hear it but the sound resonating inside car is very loud. It is plumbed right and is not starving for fuel. Have you heard that clicking before?

I'm surprised it makes a clicking. I'd figure the sound would be a wooshing more than anything since the diaphram isn't really in a state of either closed or open, but always changing position based on manifold pressure.

Yeah, the firewall probably resonates it quite effectively. Mine is mounted to the driver shock tower as seen here:

Another common area is on the front of the upper intake manifold. That's the position I am going to use on my Cosmo since it makes for a cleaner install.
