vacuum diagrams

I have a 73 buick gs with a 350 4 barrel that has been sitting since 1989 and we just got it running but we need a under hood vacuum diagram to replace the brittle and missing vacuum hoses.

have you checked with your local buick dealer?they can still get alot of those OEM parts.

i havent worked on a 73 but if they are the same as the 72 i should be able to get you the hook up. are we just talking the vacume advance? if so be aware that the temp controled vacume valve probably is bad if the lines are brittle. i have found some engines operate fine without this & some do not. my 69 buick 430 would never work quite right by bypassing the temp valve but my 72 buick 350 seemed to work just fine without it. i dont have the proper hook up commited to memory but i will check & try to post tommorow let me know if this is what you need.

An oe shop manual is always recommened for these old cars.
