Looks like a cold morning start up to me. Typical sending unit shows as pegged. The reason for that is the internal seals go bad and oil leaks into the electrical of the unit. That shorts out the sensor and sends a direct short back to the gauge instead of X resistance.
See normally my pressure is at or just above 40 while stopped and at 60 while driving. Today is the 1st time this has happened and it'* just kind of all around the gadge. I'm not used to seeing 60 while stopped and a smidge over 80 while driving. I dunno, I thought maybe it was the start up myself, but its still doing it.
