I like the fuel line to be OUTSIDE the rail ... where I can see it and repair it if it leaks ... I also find that if I install a inline fuel filter about half way, I can get from the rear to the front of a 32 with only the fuel filter as a junction. My parts store has 6 foot and 7 foot lines of 3/8th tubing.





I always install the battery under the front seat ... where the battery cables do not have to be very long to make it to the starter ... and I always install a cut 0ff switch ... so installing the cables inside the frame rails ... is not really a thing I do.

Just my nickel and my old timey curmudgeon way of doing things.
