87 smogged 2F:
Upon removing the carb for rebuild, I spotted this dry rotted piece of plastic that has 3 vacuum hoses attached- sitting on top of what appears to be a typical bolt, screwed into the intake manifold…
Looking into what it could be, found that it is the Gas Emissions Filter for the Air Intake (??)
From what I can make out in the emissions manual, this dry rotted cap looking thing is supposed to be pulling manifold vacuum where the bolt is screwed in…is this correct thinking?
If so, I’m assuming a PO plugged the intake with a standard bolt, and there is no vacuum on these 3 lines.
I supposed a couple of questions would be:
- What is (or is not) happening since these are open to atmosphere?
- If I need to connect them to manifold vacuum, does anyone have an idea on how to go about this?
- Currently, my AC is not working, so I could potentially run a 3-way vacuum line from the AC idle up/ brake booster port on the intake manifold, if the correct routing is too difficult to obtain. What say you?
