Out for a drive the other day and during a routine scan of the gauges I saw my oil pressure was at zero--I pulled over and the engine wasn't making any bad noises so I stopped at an auto parts store and picked up a mechanical gauge--Oil pressure confirmed at 65 lbs
My question is this--Is there a gauge that will fit in the gauge pod on a '73 Mach 1?--Maybe one with actual numbers--Electrical or Mechanical
Definitely check all the wiring and replace the sending unit before you tear the dash apart. Modern auto parts store sending units are notorious for premature failures. I would suggest trying a NAPA brand sending unit. That's no guarantee, but I've had good luck with NAPA electrical parts. If you can find an Motorcraft sending unit, even better.
