yabogrow Posted September 17, 2014 Share Posted September 17, 2014 I am in the middle of a carb swap from a carter-weber to a hitachi and I just got the new intake in but the vacuum line cp (hard vacuum lines under intake) are different. not sure what to connect to what. curious if anyone has a diagram or information. thanks Link to comment Share on other sites More sharing options...
ferox Posted September 17, 2014 Share Posted September 17, 2014 It's too bad you already installed the manifold. Unless you are doing a stock restoration you can just unbolt the hard line cluster and get it out of the way. Unfortunately it unbolts from the bottom of the manifold. Many, if not most of those routing lines are for emissions control equipment that is obsolete and should be removed if you haven't done so already. Here are a few pics of the vacuum lines you need for the Hitachi. This is an '83 Hitachi btw. Make sure you know the difference between ported vacuum and manifold vacuum. Also, the vacuum line that I have labeled as vacuum gauge is referring to a temporary diagnostic connection point and isn't necessary for your purposes.
