Hi all,
I would like to know how this valve? is called.
Also, think the routing of the lines are, one to transmission and the other one to anti-backfire valve (red arrows) in Thermactor systems. But where is the yellow one going to.?
Thanks,
Josep

Josep,
It's not a valve, it's a vacuum "T". One tube goes to the power brakes, and one to the automatic transmission. A cap covers unused ports.

OK Jim, vacuum T, thanks.
The unsused port is the one used to connect the anti-backfire valve. Right on the one going to transmission. So, the one with the stuck in the piece of rubber goes to power brakes.? You mean disc brakes.? My car has front disc brakes.
Ps: Checked the word brake booster/power brakes, no, my car hasn't got that, so that's the reason the outlet is cancelled.

Josep,
Your car should not have factory front disc brakes as it is a 200 I-6. In your picture, the metal tube on the left from the "T" that transitions to a rubber hose, is usually the one for power front drum brakes. (I can see the mounting bracket for the smog valve in the background.)

Got to ask - isn't that picture from a V8 application? Connections and purposes would differ between a V8 and what your building. Also remember not all nipples were used on every car. The vacuum block on a T code looks similar and may be the same. Connects below the carb with the large screw in fitting facing the front of the car and engine The rear most nipple attaches to back fire valve on a Thermactor manual transmission (One on the far right in the V8 application). Threaded fitting attachment in that application has a plug in it
Manual Transmission T code with Thermactor

On a T code with automatic (with and without Thermactor) the threaded hole in the fitting is used to attach a long specifically bent tube that narrows at the end to provide the vacuum to the automatic transmission and shown in the picture below. If the car was a Power Brake automatic T code then the long steel tube was attached to the power brake unit then a plastic fitting and check valve on the front of the booster connected that connection to the thin automatic line positioned at the top of the bell housing

No Jim, that was probably an upgrade made by a PO. Disc brakes was only optional to V8s in 66.

It is Jeff, I was just showing this pic because it looked the same as the one that has my car

So, for what you say, and being my car automatic, looks like this is swapped in my setup. The threaded hole in the fitting should go to the transmission and not to be stuck by a bold. Now, from the explanations above, the rear most nipple should connect to the backfire valve, in Manual trans, also the same for auto..?

Red arrows, if I have understood, the way to be
