Just forward of the oil filter - it should have one wire going to it.

And it is a royal pain in the butt to get at!!

I just replaced mine back on Saturday - it did fix my guage, and stop the hemmoraging that my truck was suffering from though, so I'm glad I replaced it.

Pull the wire off the sender and short it to ground. The guage should sweep, if not the guage is bad.

90 sounds pretty high, unless maybe a previous owner put in a high pressure pump. What does it read when it's hot? My 351 hits about 65-70 cold and drops to 45 hot running down the highway. Fresh motor, with a stock pump.
