Depending where you take your power for the gauge it may be a case of power outage to the gauge itself (power reduction relay or something like that) cuts the power to gauges and other stuff like radio/lights etc.

No difference, same oil gallery.

Remove the gauge and see how much oil is gushing out.
If lot's, you probably have oil pressure.
If trickle, I might be worried it's that one way valve.
