75 front-back fuel line replacement
Hello, I have few questions. I have been looking at the fuel lines and
brake line condition on my 75. I see considerable rust at a couple points
on both the front to back fuel line and the vapor return line (and the main f-r brake line) -- none are leaking yet. They do need to be replaced at some point in the near future.
I understand that the fuel line on the passenger side would require a
removal of the body- not something I'm ready for yet. What about the other lines?
Do I have options on replacing these lines without a body off scenario?
I am not concerned about keeping it original at this point - just fixing it
so it's safe. Does someone make such a line?
I have already replaced all the other brake lines with the exception of the F-R and rear L-R lines.
Thanks in advance..

All can be replaced with the body on if you're willing to use some compression and/or flare fittings. 
I replaced the main f/r brake line with a pre-bent one with the body on. Easily done.
I replaced the left/right one on the rear crossmember with a stick of brake line from Autozone and bent my own, you could also buy the prebent one and do it that way.
I replaced the fuel line and return by buying pre-bent lines and cutting them under the passenger seat and in the rear wheel well. Reinstalled with compression fittings.
The vent line for the gas tank I used 5' pieces of brake line (Flare fittings already installed) from the tank to the vapor canister. 2 joints-one under the driver's seat and one in the rear wheel well on top of the frame. You'd need two threaded unions.
I did have the rear bumper cover off which made the tank fittings easier. Other wise you may need to drop the tank.
