Default Vacuum routing help

Hello everyone, happy 4th. I need some help. The previous owner of my 1998 xj8 left me a mess. They pulled out all the vacuum lines from the engine an i cannot locate the proper routing. I need to know starting at the vacuum reserve tanks(below air box) the way they go. they should continue to intake, fuel pressure regulator, throttle body and continue to valves(under drivers side cover, next to brake booster) I cannot determine how and where all of these spit (tee) off. Please can anyone take a look at theirs and detail this for me. Nothing is connected even to throttle body, not to mention if i push cruise switch it causes system to go into limp mode. Thanks agin for any help.

Have you looked in JTIS for the schematic diagram? I do not have an AJ-26 NA and the AJ27 or AJ26 SC are different, I suppose.

Default vacuum routing

Thanks for reply, I had checked through JTIS and could no locate any vacuum routing diagrams and the sticker under hood was to vague to understand exact routing. I was hoping someone could look under their hood an describe the route. thanks again.
