I haven't had vacuum boosters on my vehicles for a while now. I think my GTO had it from the center carb port though.


This makes me think your vacuum is from your intake manifold and not the carb. Is this right? If so, then there are vacuum ports in the edelbrock intake that you can just buy a fitting from the local hardware store (ACE or TrueValue type store usually has it...Bigger box stores may not). They're usually cheaper than the autoparts stores too. I believe the edelbrock is 1/8" NPT. You'll want to verify to make sure.

I'll look on my photobucket see if I have a picture but if not I'll take a picture tonight for you. On the q-jet there was a how they described it in the video was a vacuum port for power brakes in which i have.

About vacuum ports I do have some on my intake manifold actually on top of my thermostat are my other vacuum ports I know one is for me to bypass the original air equipment so I could have the headers and another is supposed to be a transmission vacuum does that sound right? And then the PCV valve too.

Awesome I found a picture! when you look at the picture duane in the right lower corner you'll see a bolt sticking out that's what the brake boosters line was connected to. I tried and tried to get it off it just wasn't budging at all maybe I'll give it a go at it tonight, I could always use my impact gun I suppose? Here's the picture though.
