Did you try a mechanical guage?

A coherent post might help.

I wouldn't run it. The last Mellings oil pump I bought had a 80 PSI relief valve, which I think is too high. That would be the absolute maximum I would use.
If it goes over 80 I would be taking the pump out to check the relief valve.
*******!!! What PSI gauge??

Do you have matching sender 50 or 80 lb and the correct gauge, either 50 or 80 lb . A mix up could give you the results you’re getting.
