1991 Ford Ranger oil sending unit.

[CometFan]

I have a 1991 ranger 4 cylinder with 8 spark plugs. Where is the oil sending unit located. I have been told it's on the right side. I have been told it's on the left side. Anyway, I haven't been able to locate it. Must be very hard to see?

Welcome to this forum! I've moved your thread into the Ranger section. Check Autozone's website for a link that says component locations. It has diagrams of the sensors on the engine.

...The Oil Pressure Switch is located:
Under hood, driver side, upper engine area, above transmission housing, mounted in engine block
