Default What part is this, broken off....

Well, the part in the photo broke off this morning while I was inside the passenger wheel-well, any help is appreciated..

Where my thumb is, is the one that broke off.....what function is this set-up of tubes, looks like some type vacuum lines?


The box inside the passenger fender-well with the X on it is where it broke off from, under the bottom






Thanks guys....

They are ALL vacuum lines and need to be operational.
One comes from the back of the manifold as the vacuum supply.






One goes to the HVAC Damper doors:




and the other goes to the A.I.R. pump outlet valve.



Some people have just added a brass fitting on the bottom of the tank and that works fine instead of replacing the entire tank. If it were me, I would tap the bottom of the tank for the fitting and then glue in the brass fitting as well as screw it in.

Thanks BC, I found this older post from you explaining that exact fix. I've removed the reservoir, that was a task.., and will work on it tomorrow. Here's your old link, #11 post...
Once I realized they were vacuum lines, I didn't want to just plug the line that broke off the R-tank, but seems I've read some guys did exactly that.

Appreciate your help.....
