So a couple weeks ago I installed a boost gauge. It read 20 inHg vacuum, which is normal, and was only boosting to about 5 psi. The next day, I got nothing on the gauge at all, the day after that I got like 1 psi max and no vacuum. I found a broken vacuum line that was broken before the gauge install (see: !!!error: Indecipherable SUB-paragraph formatting!!! ) and patched it today. However, the gauge still doesn't work. I reset the engine code I had and the car runs fine and everything, but still no response from the gauge. Do you think it will eventually kick in after a certain amount of driving, or should I keep looking for problems? What's killing me is that it was working fine when I installed it, and it just suddenly quit.
(Gauge is tee'd into the fuel pressure regulator)

Gauges don't have "break in time", check the line that the gauge is working off of. Maybe the gauge just shit the bed
Also I wouldn't tee it off of your FPR. Tee it off of something thats not important, regulating your fuel pressure is kind of important.

Yeah I know gauges don't break in, I was just wondering if the broken line I found that I patched needed time before the ECU tries to send air through that part again, and since it was right next to where the FPR attaches to the intake manifold, it might have had something to do with the gauge not working.

The ECU won't reroute vacuum if it senses a line is broken, because it can't sense a broken line. At most you'd get some code related to a vac line.
Trace the line you have on the gauge again and make sure its leak free. If you're 100% sure the line is okay, test the gauge itself. What kind of gauge did you buy?

Pictured above, Sunpro. I checked everything already and it was all airtight, I guess I'll just have to check again. Maybe the gauge is faulty like you suggested.

Didn't want to assume but I figured that was it.
I'm sure theirs a method to test boost gauges so I'd do a little digging on that.
