No Oil Pressure

I thought maybe I blew the pump seal and was filling the crank case full of diesel, but the oil lever is fine (although the oil does look a little thin). Since it wasn't rattling I drove it home. The gauge kept falling until it was back to almost zero. Still, it sounds fine.
Probably the sending unit right?
