Just a couple of questions about vacuum/boost lines.

Does it matter what type of line I use?
What is the difference between using the manifold vacuum ports, the accessory port on the carb (which should be manifold vacuum), and the nipple on the compressor?
What should be hooked to the boost gauge?
What should be hooked to the fuel pump?
