Re: '71 air cleaner & manifold help

Problem: I am unsure of 2 items that are coming off the air cleaner and believe they will give me a problem when in install headers. So, I am looking for help identifiying them and finding a work around.

Yellow arrow: what is this yellow tube that runs from the air cleaner to the exhaust manifold. How does this come into play when installing aftermarket headers?

Green arrow: looks like a vacuum line that runs from the air cleaner to the side of the carb. If i need a new air cleaner to fix the above green arrow issue how does this vacuum line come into play with the carb?

Any help or suggestions is greatly appreciated.





Welcome to the board!

Looks to be in nice condition. If that was my grandpas truck I would just put the duals on the stock manifolds and drive it the way it is for a while. Don't be in a hurry to make a bunch of changes to it until you make sure it's what you really want to do. How about a few more pictures?
