Vacuum help
« on: October 11, 2010, 10:25:43 pm »
I have a 1977 siverado with the 350, 4bbl quadrajet. I was relpacing valve cover gaskets today and had to remove some vacuum hoses. After replacing the passenger side I have mixed up the vacuum lines. can anyone help by telling me which ones go where.(including the ones coming from air cleaner)  Thanks to all for your help

you should have a silver sticker label on the radiator support by hood latch showing vacuum diagram.
This is from my '79, which should be similar to your '77....

I have the sticker, but it has fadded and can no longer be read. Thanks for the pics I will see if i can match any with what I have. Do you know where the two coming off of air cleaner goes? I think that will help me narrow it down alot. Thanks Again!
