Intake pipe going to welders. How many vacuum ports does it need?

[MarkIII4Me]

Does it only need 2?

One to the valve covers and one to the power steering pump?

I keep thinking I'm missing something.

PCV, ISC on top (and BOV unless you vent to atmosphere)
power steering on bottom.

I'm running a VPC so BOV is vented to atmosphere.

FFIM is provisioned for ISC; so that's what I'd be missing.

Thanks cush.

You could just get a nice sized port put on and run a vacuum manifold.

That's an idea. Would be fine for the PPS pump vacuum. However the PCV and ISC ports are pretty large; so that vacuum manifold is going to be pretty unsightly to keep those port sizes.

Where does one source the vacuum nipples? I'd just rip them out of the accordian hose, but I'm pretty sure they're steel where as my intake pipe is aluminum.
