TVS Valve
Looking for some help with the vacuum line plumbing for the TVS mounted on the base of the breather cover. There are two ports on the switch. The Ford part number on the switch is D5AF-9A995-CA. The carb is a 2150 on a 1977 Canadian truck with a 351M. There's no Thermactor on the engine.
Thanks guys, really do appreciate the help.

Check with Mil1ion. He has several vacuum diagrams. The TVS could be routed different ways depending on applications.
On mine, one port goes to the AIR bypass pump. The other...I think to a thermal vacuum switch on the water neck.
