How to replace oil sending unit on 1988 chevy pickup

SOURCE: 2001 chevy venture oil sending unit

HI..
On a problem with oil pressure sensor leaking.
99% you need to replace the sensor with a new one.
Because if you can see the leak is not for the tread or gasket of the sensor.
If you can disconnect the the wire from the sensor.
and try to start you will see the leak coming from inside on the plastic, where the pins. of the sensor.

OK.. I hope this information work for you.
I work on Cars everyday.
Thank you fo use fixya.

It should be on the rear top of your engine block next to the intake. Three wires goes to it if its a 4.3

It is located at the very rear top of the engine block behind the intake manifold and just to the side of the distributor.
