Fuel Cell Location

[BrentRS1985]

so I'm about to put a whole new fuel system in my truck (fuel cell, holley black, steel braided fuel line) and I'm trying to figure out where I want to cut the hole in the bed for the fuel cell. I was thinking as far back as possible while still being protected by the frame rails. Also, I remember hearing that the fuel cell needs to be grounded, do I just run a ground wire to the frame? Do I need to ground an aluminum fuel cell? Where on the fuel cell do I put the ground wire?
Any help is appreciated, thanks!
