1985 EA82 GL Intake manifold vacuum line port questions

[Turkeyberry]

As the title states  I have questions regarding some ports/lines. Any help would be greatly appreciated.  I'm almost done with my 38/38 synchronous swap(regrind cams next). A few notes, distributor vacuum advance is already plugged to Carb with a direct hose. All emissions stuff is/will be removed. I haven't had much luck looking up specific diagrams so these questions remain. This forum has been so useful in helping me get this far. Once I sort these I'll be back on the road! 

 

pic 1: fuel line is 1, has filter. 

2 is return I guess?

3? Was plugged with this when i got it, had to tow it home, carb was jacked up, manual choke swap[cold weather up here] got it running but secondary wouldn't work properly, and other issues. As well as all sorts of weird stuff  going on with lines like this

Pic 2

No idea on these? Can I plug them all?

Pic 3 same on these 2

Pic 4 little guy hiding here.

If in doubt, plug em all off for starters - I do

Not seen the horizontal one #3 beside EGR mount before.

EA82 if you said plural cam

One of those vacuums must feed the plastic vacuum reservoir up near strut tower that feeds the dash control switches.

Most others look to be carb and pollution related or cold start assist things that 38/38 don't got

The # 3 one above the EGR looks like the thermal sensor on my EA82 from California.   All it does is tell the ECU that the EGR actually opened.

Thank you for the replies! I capped all. And it ran fine.
