I would suspect the sender maybe at fault? Or if the harness section for the senders has a grounding issue? What does the oil temp behave like at start?

Guys,
The bouncing ONLY occurs at startup. I crank the motor, needle sweeps to 80, then sweeps back down, then back to 80. Once running and cruising it is fine
and registers proper pressure which is usually right at 60psi.
Could this have anything to do with the Oil Filter? I am
using a silver Fram TG
