Welcome to the Diesel Stop
The factory dash gauges are a joke to say the least. If you want to monitor your oil pressure then you can put in a mechanical or electrical gauge. The factory sender is in the top of the block in the middle at the back.
At operating temp the oil pressure for the IDI's is about 12 PSI @ idle and about 40 at higway RPM's. These engines are lubricated by VOLUME not pressure.
Your choice to tee or just replace the sender. My truck is turbo and I have a tee to watch (HaHa) the factory gauge sit and an aftermarket gauge on my pillar to see what is really going on.
