What is going on?
A couple of weeks ago my fuel pressure gauge (AutoMeter) quit working...there didnt seem to be any difference the the cars performance...then a couple of days ago I glanced at it and it was reading 45 lbs. as it used to. Then a couple of days later I got into the car and started down the road and the gauge was reading 0. A few minutes into the trip the fuel pressure slowly started to rise. About 20 minutes later the pressure us up to 45 lbs. Any ideas as to what the problem might be?

Pull the weather pack on the sending unit and check the voltage. If it is reading .6 vlts on the grey and 7 vlts on the purple at idle, your gauge has bit the big one. Send it back to autometer and they will send you a brand new one. No voltage at all? Check for 12v at the red wire at the gauge. Good there? then you have a short somewhere in between. I don't know how you wired your gauge, but mine slid under the clutch pedal once and severed the wires. Let us know what you find...

Also check the sock on the fuel pump. I have seen some posts on the forum regarding this job - I will be doing it myself soon.
