Hi:
first, if the engine isn't making any noise when your gauge drops, chances are it's the sending unit. Yes you can check the pressure with a gauge. Most parts stores will rent the gauge for next to nothing, so don't waste your money purchasing one. Finally, I believe your sending unit is close to the oil filter.
Let me know if this helps.
Joe
