intake fittings

I have found a vaccum fitting for my intake with the ports I need but have a few questions. First is the vaccum hole 3/8?(edlebrock air gap dont think it matters tho)

Second looks like the PO used some kind of goop silicon or something when I remove the old fitting and clean the hole what should I use to seal it (I was thinking plumbers tape or something.) And about how tight all the way in till very snug or just so long as it is in a fair bit?

Thanks for your help I know this may seem easy just never done it before.

Re: intake fittings

Not sure on the first one, you could use any that provided enough vacuum.

I use teflon (plumber's tape) anytime I am working with vacuum or compressed air.

Re: intake fittings

I guess on the first one what I mean is, is the threaded hole in the intake 3/8inch?

Re: intake fittings

Careful not to over tighten the brass vacuum fitting in the aluminum intake as there's a good possibility of cracking the alum. casting. Just snug, maybe 20-25 in. lbs. and 3-4 threads left showing on the fitting. Nice choice in the Air Gap intake. My guess is 3/8 pipe thread. Oh, definitely use teflon tape.
