Pressure gauge problems??

[Labhunter]

My gauge normally reads 60 for vo and 75 for diesel. All of a sudden yesterday, it started reading 75 for vo and 100 for diesel. What up?? Any ideas. My theory is something in the gauge because it is on both sides.
Is there any possibility of a problem in the fuel line itself, or another possible problem?

I would suspect the gauge. Is there any way to hook up another gauge to check your pressures. I have a schrader valve in the line from the fuel bowl leading to the sending unit/gauge.

I am guessing the gauge too. Otherwise, it would only be on the side that was having a problem. Could it be a ground issue.

Yes, we are going to put a gauge on it to see what it reads.

Thanks
