Oil pressure dropped to near 0

As I pulled into my drive way the oil pressure in my jeep dropped to near 0. It is not smoking and in the three months I have had it I have not added oil and the oil is still reads full. I am thinking it is the oil pump but I am no great mechanic. Any suggestions.

Might be the pressure sender, should be on the passenger side of the engine block, about in the middle with a green wire coming off of it. Wiggle it and see if it changes at all.

I just went out and looked at the sender, It is not a wire but a tube. It has aftermarket equus gages. The tube has oil in it but it is not full. There are many air gaps.

Those air gaps may be causing your 0PSI reading. Time to figure out why there are air bubbles inside of that line..

Send a message via Yahoo to Nubby55
If the lifters are not rattling a lot then you have oil pressure.

From Equus tech

If you are seeing air gaps in the line. That is indicating that there is air in the line. The line will need to be purged, which means the air needs to be removed. To purge the line, open the line from the back of the gauge slowly until the air is out you also need towel to trap the oil. You will need to have the engine running to purge the line.
