I did lines on a van for someone with straight line from the parts store. I have a bender and it is not that hard. I also did not try to duplicate the factory routing. I just ran the lines down the the path of least resistance. Why run them along the fuel tank so they can rust out sooner ? I was also working free so I could do it my way.
Anyway you can do it faster and easier if you do not worry about every little clip and bend the factory uses.
