Scott,

That's the gauge you are looking at, not the sending unit. I don't need the
gauge.

Thanks,
Mike

Mike,

My Feb. 1995 Cherokee parts catalog shows the sending unit on Figure 68,
"Electrical System Installation", item #63: "Gauge-Engine Unit, Oil
Temperature" Depending on your Serial # ( 20550, or 20550 ), it shows
Piper part # 462-046, or 550-487 (mfg's part #'s 1514976, or 362-EW). Bear
in mind all of those #'s have probably been superceded by now, but perhaps
a Piper dealer or Lycoming distributor can take you from there.

Happy Flying!
