i have a 94 jimmy with the 4.3 L vortec and i wouldlike to find a vacume line diagram if anyone knows where i might be able to find one online that would be great thanks

What vacum diagram are you looking for?
Engine or AC-Heater?
Does the dealer still have a factory repair manual that he can copy the diagram for you?
Can your dealer still get the engine routing diagram?

i want the engine and im not sure if the dealer has one i didnt think to even try them but it would be nice if i could find one online so i dont have to go down there

I got mine from the online dallaslibrary.org. If you have a library card then it is under the all database link.

I cant seem to get that to work for me does anyone have any other suggestions it would be greatly appreciated
