The oil pressure sending unit is directly above the oil filter and hugging the block. In order to damage it you'd have to come in through the top or the radiator. Now assuming you did somehow brake it without taking out the oil filter (something not on the list) You would spew all the oil in the engine out in a mater of 30 seconds and you don't have a new one, or a pipe threaded plug to put in its place.

Actually I was out hunting with an old-timer I work with, we crossed a river in his YJ and for what ever reason (I assume thermal shock) the oil pressure sensor cracked, he had tools and spare nuts & bolts. He took the sensor out, and replaced it with a bolt he had - problem solved, otherwise we would of had a really long walk. I fact I am prety sure that bolt is still there since the sensor is made of plastic he didn't want to replace it.

I guess for some ignorance is bliss. I personally don't want to always be dependent on others to save my butt, I would prefer to be as self sufficient as possible. You are corrct, there are several places where the list can be reduced, channel locks and vise grips and pliars is a little over kill, and I am sure that I will figure out what I need and don't after a while, but that is why I posted.
