Shaky fuel pressure guage.
I'm running a AFPR and my hypertech guage pin bounces like crazy. Is that normal. I'd like to rule out a bad AFPR (no fuel leak through vac line).

When I check my fuel pressure the gauge is fairly steady, moves a little but not much. I'd be more worried about the fuel pump than the AFPR. I'd check with another gauge before doing anything else.

That happened to me when my fuel pressure regulator bent and got stuck completely closed, I turned the bolt down a little to far and it put a slight bend in the regulator. I went back to a stock regulator and problem fixed.
