Rod,
I finally found it. The Motorcraft part number is CX-1628.

So now my challenge is finding one. I'm seeing that they are discontinued and don't know what my options are.
I greatly appreciate you staying with me on this! As part of the secondary air injection system, a tube leaves the air pump and takes two paths. One to the front unit and one to the rear unit. These units are vacuum operated.
Any suggestions in sourcing something like this will help!
Thanks..... John
