Help ID part. Reading therm. transmitter?

[Matt Ellena]

Hey Everyone,

This part fell off from my firewall and I am having problems identifying what it is.  Can anyone help?  I think I found it in the Haynes manual as a "reading therm. transmitter" but can not find any information online.  Does anyone know if I can still buy the rubber that broke?  Any advice or insight would be awesome.  Still learning to wrench.  Thanks!

That is a vacuum solenoid valve that is part of your emissions system. If it wasn't connected to any thin rubber hoses then I wouldn't worry about it. Someone has already taken it out of service. 

 

Don't know where you are and what your smog laws are like but search on this site for details of 'de-smogging' or removing the emissions equipment.

Oh nice!  I live in California and the car is a 72 so its pre-smog so I do not have to comply with any emissions.  As it broke from its mount can I remove it?  Thanks for your reply!

Like I say, I will defer to others on the finer points of California law but if that's the case there are a number of redundant things you can remove.

I doubt that is a sensor, it only has 2 wires on it and the case isn't grounded in any way.

 

If there is no vacuum line running to it, then it's doing nothing and you can safely unplug/remove it.

Thanks guys. I'm going to unplug it and see if I have any issues. Looking around it appears no vacuum lines or anything.

It looks like it has a white top, which pulled vacuum from the intake manifold and activated the dashpot on the Solex 2 barrel carb.  If your Solex carb is long gone, you can remove it and throw it in your neighbor's pool.

PO replaced with a weber.  Pulling it tonight!  Thanks!  Less crap in the engine bay!
