??? Are you talking about the sending unit or the gauge? The gauge goes in the dash if you're talking about a factory gauge. The oil pressure sending unit goes in the oil gallery which is in different locations depending on year, engine etc.

I was told that the sending unit behind the distributor isn't for the gauge reading.  The bigger sending unit above the oil filter is where the gauge gets its input, as shown in SgtDel's picture.

The sending unit as shown is for the oil pressure guage.  The pic is from my '79.

A smaller sending unit is also in same place in my '91 5.7.  It too has an oil press. guage

Either location can be used for Pressure.  The one at the top is the further away, but there isn't any passages between the 2.
