Looks like Roscoe placed his fuel lines, filter, and pump on the inside of the main frame rail, and these items don't seem to be protected from the drive shaft. Just my opinion, but I wouldn't install any fuel lines, etc. where the drive shaft or any other moving item could get to them. Drive shafts tend to do funny things when a U joint fails. I know that most guys use drive shaft safety hoops but still, better to be safe than sorry. I installed all my fuel line, filter, and pump on the outside of the main rails well away from any rotating parts. As previous posters have suggested, the last piece of tube should be flexible, not hard, to allow for vibration and flex.
