Adjustinf fuel pressure regulator?

How do I adjust my bbk fuel pressure regulator? It's set at 40 I need to adjust it down to 32. How do I adjust it without messing anything up?

Re: Adjustinf fuel pressure regulator?

To adjust the fuel pressure, disconnect the vacuum hose and plug it off temporarily to avoid a vacuum leak.

Restart the vehicle and simply adjust the top adjustment screw in or out to raise or lower pressure to your desired reading (stock pressure is 39 psi).
Once the desired pressure is reached tighten the lock-nut and reconnect the vacuum line to the regulator.
