Thanks guys. By the way, I did not intend that Techinspector or Denny were the only ones who could answer.

I am using full manifold vac for brake booster (a fitting directly on manifold). Is there any reason why I should switch to the carb port (planned to plug the carb one, brakes work great on direct manifold)?

Why would I use the high speed crancake draw port? I can't think why I would use that.

Finally, I noticed another port just below the fuel inlet you can see in the first picture (passenger side low). What is that for?
