I'm finally getting around to installing my fuel tank and new lines for my EFI system. I am running a ZZ4 and will need return lines. For those of you that have changed out your lines to larger ones... How did you do it? Hard line, or braided line? I like the simplicity of the braided line since I'll need to run two, but is it safe to run the full length of the car? Since there is not a full length frame how do you keep it safely routed?
