My 72 has the same piece on the air cleaner. so i dont think it was only that one mine is a CA car and it had it. with the AC on the top and everything.
im under the assumption it is a temperature controlled vaccum valve. mine has the two ports and one side goes to the intake manifold and the other side goes to the Vaccum operated valve that opens and closes between pulling in air from the top air horn and the bottom one that is ducted under the motor.
thats my take..maybe its just mine.. but hope it helps..
#5 on the diagram is my AC branded valve
Your diagram helps a lot & I believe it's spot on. Now it's starting to make some sense! Thanks!
But......question is - can this part be replaced, because I broke one of the vac legs removing mine? I mean I know how to replace it, but are replacement parts available?
