Where is the Oil Pressure Sending Unit located on a 1990 Ford F-150 with a 302 motor?

The oil pressure sending unit on a 302 ford is located on the block of the engine. It screws into the block and the sending unit goes on the end.

The oil pressure sending unit on a 302 Ford is slightly above and to the left of the oil filter. I find it is easier to replace with the oil filter out.
