i would use brass fittings in everything except the turbo feed. i have had the brass fitting break on me from the heat. if you are buying fitting maybe you should just look into the xrp, earl, or russell fittings from your local speed shop. if you dont wanna do that, go to amazon and get steel fittings, not brass.
