I'll probably take a lot of abuse for this, but I'll share a couple pics of mine.
I printed up some fuel line clamps to hold the pressure and return lines plus the air line for the rear locker and the rear brake hardline. It has a cradle on top to zip-tie the wire loom into as well (there is a heat shield to cover it, but off for the pics). Fuel filter mounts on the outside of the frame rail for easy access and minimal heat. Low pressure pump with pressure cutoffs to transfer fuel from side tank to rear tank if I need more capacity. I also printed an air cleaner spacer to get up over the return line out of the FiTech. Gauge on front allows pressure monitoring at the TB.
