I noticed this was not plugged in to anything while rebuilding my carb. Is this why my tachometer doesn’t work? Anyone know the part number and where this plugs into? Located in front of the carb on the thermostat housing. This has snapped. What is this this for? And what’s the part number? More views below. View looking towards fan and shroud. Alternate view.
The first picture, that doesn't plug into anything. Only used for a tach/dwell meter when servicing.
Picture 2-4 is the Purge ported thermal vacuum switch. Rockauto has them. It's listed in electrical switch and relay section.
Agree with both above...
If a replacement filter were purchased from GM the box may or may not have had the instructions on it.

All help is much appreciated!
I think I can faintly make out a part number on the top.
It also looks like to have 2 port.
I think it says 3031549, that would be the GM Part Number if so.
I believe a SMP (Standard Motor Products brand) replacement part number is PVS16
