Where is the oil pressure sensor on 1991 5.0l V8?
Haha yep. I found almost everything I was looking for there and only left because they were closing 
Thanks for the tip. I was pretty sure I'd found it when I changed the oil but wanted to be sure. Since my gauge is all screwy I checked the oil pressure today and verified that it has got 50-60psi @ 2k rpm as well as at idle.
To keep an eye on it I got 1/4" NPT fittings including a tee that I'm going to use to install a second, accurate gauge in the dash.
Thanks again

Great deal. Remember that after warm up, your pressure will probably drop to between 20 -30psi. Mine stays around 20 - 25psi at idle and 45 - 50psi at 2k rpm after warm up.
