Hey,

I am in the process of doing a frame off of my 1998 Jeep TJ 4.0 and have done a frame swap to a like new 2005 frame! I’m doing some odds and ends before putting the body back on and I’m stuck on one part since the line was MIA when I originally took the body off. I’m interested in anyone has a schematic of how the EVAP Fuel Vapor Vacuum Lines run from where they connect to the “y” at the tank all the way to wherever they go (again that’s the part that was missing when I got the jeep. I’m planning on running this line before since it’s wide open but just don’t know where it connects in when it gets to the engine bay. I appreciate all of the help!

It's all detailed in the Factory Service Manual, found in the Resources section on this site.

Congrats on getting this far on a frame up without having the FSM!

Awesome I found that entire routing in the FSM. Thanks for the help!
