I'm hooking up the oil pressure gauge in the same panel as the water temp (other post) and the sending unit for the gauge is HUGE. Not a chance for it to fit in the stock location. The oil filter, fuel pump, and PS pump are all right there. A buddy told me to try to plump it somewhere else, but there isn't really anywhere else to move it, unless I go out about five inches, and down about another three. I did see a plug on the block on the passenger side. Not sure what it's for. It's right behind the alternator, below the head. Is that also for oil? Could I hook up the guage to that?
