Pluggin up or hooking up w/Weber

When I went from the Holley to the Weber, I lost some of the connections I had for some of the vac and crank case lines. Plus, I can't remember how I hooked up some of them. I now have 3 places that I just plugged up, but I don't know if I should or not.

1 is on the rear plate
1 is on the oil filler neck
1 is beside the oil filler neck

Also, I had the trailing advance plugged before and the leading was hooked up with the holley. Should I just plug the leading now too?

Here are pictures. Thanks in advance....

the one on the rear plate is a water source for a tb just cap it and put a clamp on

the other 2 need to me hooked to a vac source with a pvc valve or with a catch can for the water.

this will create a vacuum leak, unless you have locked your distributor. otherwise plug them up (i ran mine like this for about 4 years no problems) but it runs smoother if you "T" them up and run a constant vacuum for it.

With a Weber and the Manifold with it, where is the best place to hook up a vacuum? I drilled into the manifold to plumb in one for the brake assist. I'd rather not redrill in there, but I can if I have to.

Should I drill and tap into the manifold to get a place to pull a vac like i did for the power brake assist?

i'm not running vac adv and i don't have them capped off. they're not a source of vac so how can they create a vac leak? they need port vac to operate, otherwise they do nothing.

The iron needs a PCV valve to a vacuum source (I teed off the brake booster line), the filler tube just gets a small filter.

All of the aftermarket intake manis I've seen have a barb for brake boosting and another for vacuum. 3/8" NPT for brakes, 1/8" NPT for vacuum, (in the primary runners). But I suspect you're still running the SE LIM so that won't apply. Drill and tap for vac advance. If you're going to run vac advance, run it for both leading and trailing.
