my gauge was fine when I first started my car but after about 4 or 5 min of driving it would go to 0 and the check gauges light would come on. I checked my unit and it was leaking out of the top and onto the crank sensor cable so by default I had to replace that as well.

Would the oil pressure sending unit cause the oil gauge to fluctuate while running?

Yes, I'd be driving down the street. All of a sudden I would hear a chime, check engine light would come on, and oil pressure would mark zero. Really scared me until I read this thread. I think I sold the car before I fixed the issue though.
