I am sure you can. Just deppends on what lines you are talking about....or are you talking all of them?
I use the online parts fiche at www.cyclemaxohio.com OEM section to look at my parts on my wing. Sometimes it helps to see where things go. Just click on OEM section and find your year of wing and then start looking. The fuel lines should be in the Fuel tank fiche if I remember correctly.
the hose is directly underneath tank,and in a position which is extremely hard to get to,making it very hard if not impossible to change w/o removing tank,at the least you'd have to remove the rear wheel and inner fender just to see it from the rear
