Brake booster vacuum line?

[scarbrow]

I am needing to hook up my brake booster vacuum line on my 1990 truck,

the 6.0 i put in had the hydraboost system in it so the spot to hook up the line on the back of the intake is pluged.

My question is how do you remove the plug from the intake?
I didn't know if it required a special tool or if it just pops out.

I just wanted to ask first so I would know and not risk breaking anything on the intake.

we used a flathead to press on the ring and it popped right out
