does any one know where i can find carb vacuum line diagrams to an 86 z-28 w/a rochchester 4 barrel carb? iv checked everywhere even junk yards for diagrams
please help. all help is much apreciated
I need the same thing but for an 85 T/A w/ lg4. I think that they might be the same, but if anyone knows where to find this or has a diagram could you please help?
There is only one major difference between the 85 carb and 86 carb. The 86 carb has an extra vacuum port. Below I have included 1984, 1985, and 1986 vacuum diagrams. Even though the 85 and 86 say VIN G, study the pics and see they are almost identical to the 1984 VIN H with the exception of the air cleaner housing, the extra port on the 86 and the way the lines run to/from the canister. These should help you tremendously, they did for me. By the way, if you clean your carb really well, the letters that correspond to the diagrams below are actually stamped into the body of the carb.
