1972 LeMans vacuum diagram

Recommended Posts

Hi all, 


new to the site. I hope i'm in the correct topic area. 

I'm looking for a vacuum diagram for my 72 Lemans 350. Just purchased the car and the hoses are a mess!!! I plan on replacing the 2 bbl carb and the intake manifold, but I need to know the proper routing for these hoses. 

Any help would be greatly appreciated.

350 or 400 2-bbl engine?

Best thing I can find online. An original GM shop manual for your vehicle is well worth the money - either as paper or as a CD.

Thanks for the info. It is a 350

I suspected as much. Let us know how you do or you still need more information or help.
