Default Oil Pressure Gauge

MY oil pressure gauge is acting really funny lately. Its jumping all over the place even without the engine running. Does the sensor need to be replaced? Where is the sensor anyways?

First, check the oil pressure with an external gauge to see if the engine is really loosing oil pressure. If the engine is ok, it may be a bad ground somewhere in the dash. Pull the dash unit and get it checked.

Sender is behind the distributor, either it or its connector can go bad, assuming that the engine isnt losing pressure for other reasons.

You'll either have to pull the cap off or pull the wiper motor to get it. It looks like a fuel filter.
