You can use rubber fuel line but if you do and it runs outside the vehicle and underneath it is most likely going to get cut by a rock or something else. This is why they use metal lines. Also, the rubber will dry rot eventually.
However, if you are not comfortable bending the tube then they do make repair kits. Just do an internet search on fuel line repair kits and you will see where you need to cut the damaged line out and splice in a new metal line.
Again, this is not the best idea because if you have multiple spots, you have a lot more joints that can leak. However, it may be your best solution and then use rubber line on any bends that you need to cut out.
Hope this helps.
