Here's the situation....

I have an adjustable fuel pressure regulator, not the B&M type. the one with the guage already attached. Here's the thing. It was working fine for a while. I had it previously set for 41. Today, I took my car in and had the ignition timing checked. Now, my FPR is reading way high. I start the car and it jumps to the point that I set it before (around 41) then jumps to around 75 or so. Weird thing is I can't make it come down at all. Opinions on what could be wrong? Anybody. Could the guage be broken?

The setup: I/H/E, Nos 55 wet shot, FPR. b16a in 95 civicEX


Thanks in advance.
