I can't seem to find it online. This is near the distributor on a L98 91.

Oil pressure? It's hard to tell but if it is on the China rail and threads into it it should be. Maybe temperature?

The oil pressure one is next to it. The one circled is something else.

Actually I think I found it. I guess it is a safety for the fuel pump.

NO

The one next to it is for the 'IDIOT LIGHT' - you've stumbled upon the oil pressure gauge and fuel pump switch for the ECM. Post the wire colors to the part you want for confirmation.

**'91 is likely 'CHECK GAUGES' = 'IDIOT LIGHT' BTW - That's a seriously high price for what you're needing. There should be much better choices using that part # as a reference.

It was just the first thing I found that looked right.
