Does anybody know the function of the tube coming off of the center passenger port on intake manifold? It travels under the intake through some kind of tube with a spiral flat metal inside. I am assuming that this is impossible to find, therefore, can it be eliminated? See pics.
OK, here's the answer. It's a warm air vacuum line that goes to the choke on the carb. The tube inside runs the length of intake, with a twisted metal insert designed to slow down the air flow. The small pipe plug allows installation. A real bear to remove without torch heat. The tube is semi pressed in and was driven out with a round punch. Info thanks to folks at AACA. Now comes the fun part of fabricating old pieces and pressing in.
