Best Answer

The location of your oil pressure sending unit is right behind your distributor. there is a spitter there with two(at least on mine) sending units. I believe the one on the passenger side is a fuel pump shut off switch (when oil pressure is too low unless you have a mechanical one) and the one on the D.S. is the oil sending unit. I have an 86 GMC Sierra and that's the way it's situated on mine.

I hope everything goes well!

God bless, Howie
