Need help on Map Sensor

On the back of my 86 intake it has a 1" hole where a pcv style valve was and on the end of it was a vacuum line going to the Map Sensor. Whats that valve or Connector called that sits in the hole on the back of the intake?

I am putting the 2000 explorer intake on and the valve/connector was just a lil bit smaller from the stock intake when I put it on the gt40 intake. I wanted to replace it but misplaced the old one first and never grabbed the one from the explorer in the junk yard so I am stuck. Please, what is that part called?

The Pcv valve?

The map sensor should not be connected here. It should go to clean vacuum either off the tree, or to the upper manifold.

The Pcv valve sits in the hole on the lower, and the splits into 2. On line to the outer plenum pf the manifold and one to the inlet underneath. Nothing else connects since this line can see oil.


All the 5.0s use the same valve. Explorer, cobra, gt40.....all the same. There's the valve, a Pcv screen and grommet. I recommend motor craft for these parts.
