I'm hooking up a NOS fuel pressure safety switch p/n 15685. The instructions are kind of vague about the switch adjustment. Should I set the switch with just the ignition on? This gives me a fuel pressure of ~43psi. I believe this is the approximate fuel pressure @ WOT. So, I guess I should have my switch activate if my fuel pressure drops below 43psi. Does this sound right?

Here's the instructions:
