Where is the oil pressure sensor on 1991 5.0l V8?
I just bought a 1991 F-150XLT Lariat 5.0l V8 and am trying to assess how well everything is working. Right now the oil pressure gauge is reading at the VERY low end of the "Normal" area, near the red line. I just filled it up with 20W-50 in the hopes of upping the pressure with a thicker oil, but no difference.
I know the old factory gauges are crap so before I sell into the 'low oil pressure' problem I want to hook up a mechanical gage and see if there really is any pressure. Problem is, I can't find the pressure sensor/sending unit. I read that it was located right behind the oil filter but I don't see any wires coming out of the motor near there.
Where is it? Thanks in advance!
