There is only one fuel line on your bike.
It runs directly from the petcock down behind the air cleaner backing plate and connects to the carburetor inlet fitting. The fuel line should have a piece of nylon insulating tubing around it as well.
The carburetor inlet fitting is very fragile and is easily cracked so be careful with it.
I hope this helps. Please let me know if I can be of further assistance. Thanks, P.J.
I'm guessing you are looking at a combination of vacuum, emission (if the bike is a California bike), and oil lines.
I'll try to get you routing diagrams for all of the above and hopefully that will help. If you can attach some pictures of what you see I can probably help you identify them.
Also, is there a reason you can't follow the routing as the lines are currently installed? Are you concerned they are not correct now?
