bogus factory gauge??
Hi all,
I just changed out my '96's oil pressure sending unit. Simple job, no drama. I was curious to know how exactly those work, so I cut my old one apart. Keep in mind that the parts store guys wanted to know if I had a gauge or a light, by the way. Well, as far as I can tell, the "gauge" style sender acts more like a switch than a variable pressure indicator. As soon as the oil hits the diaphragm, it causes the metal contact to hit a spring, which would cause the gauge to move. There would be no indication of relative pressure. Can anyone tell me how these work?
Thanks!!

find a t fitting and install a mechanical gauge that works. I bought a pod cluster for the A pillar and will be installing the mechanical oil and temp gauges there. looks kewl and is easy to see . plus its nice to know what is going on , not just guessing like those factory gauges do .

The instrument cluster is designed for the oil pressure to read either low or normal, depending on the switch. There is a simple mod to turn it into a real gauge by removing the current limiting resistor on the backside of the instrument cluster, and installing a sending unit from a pre-86 Bronco with a gauge.
