Re: Where is the oil pressure sending unit on a 1987 gmc...
- You should have two of them (which went to one in think 1991 or 1992)
- The sensor by the distributor is for the oil pressure gauge - see pic below.
- The sensor by the oil filter worked with the fuel pump power circuit see - pic below.
- If you have any comments please feel free to leave them here.
- Hope this helps and thank you for using FixYa.

Tony
