I plan on installing an oil press. guage for my 3sgte when i get it running. I was wondering which would be better, an electrical or mechanical. If its electric, what wire do i tap into to get the correct reading, and if its mechanical what oil line do i tap into to get the reading. Any info would help,thanks.

talk to Dustin

youll need an adapter for the pressure sender for a mechanical gauge.
it taps into the head, where the stock pressure switch is.
i dont recommend a mechanical oil pressure gauge, you dont want oil in your passanger compartment.
