I think i may have mixed up where my vacuum lines are going when i pulled it all apart to change my exhaust manifold. one of the rigid lines snapped at the mid point but i can't tell exactly which 2 ends to connect and which goes to the EGR. I dont have the best memory for things like this. I have a repair manual but it is too vague to follow. Any one have some GOOD diagrams to follow or even photos to see? I am really interested in the EGR area and the block that they all meet at too. It is a '88 cherokee, 4.0.
