That tubing was also on earlier models. As mentioned by others the tubes are
part of emission control and the allow fumes to be drawn from valve cover
into engine to be burned.
PO removed them from my 1970. I would like to restore them. If anyone knows
the inside diameter of those hoses I would appreciate it??? I don't want to
disturb the "plugs" on my carbs until I have the correct hoses to put back
on. Thank you.

Subject: [6pack] Carburetor hose
> I just got my '76 back from the shop after an extended stay.? In order to
solve the plug fouling problem, the mechanic made a few changes.? First, he
installed an MSD ignition box and?MSD plug wires.? Second, he spent some
time adjusting the carb settings.? The carbs themselves (Zenith-Strombergs)
were rebuilt less than 2000 miles ago.? Third, he hooked up some sort of
tubing that I don't recognize from before.? It runs from a port on the front
side of each carburetor to a T-fitting, and then from the fitting to the
back of the air cleaner.? What is this tubing for?? Is it a PCV setup?? Why
was it missing before and why do I have it back?? Anyone out there running
an MSD ignition box?

> The good news is that I took the car for 2 pretty long test drives and it
is running very strongly.? Even better, I pulled some of the plugs today
after a 2-hour drive and they looked perfect.? The black, sooty look is
gone.? After lots of time with a meter on the exhaust checking different RPM
ranges for excessive rich or lean conditions,?the mechanic?returned to the
stock needles and sent the others back to Joe Curto.

this week.? If they don't foul then, I should be in good shape.
