Mounting the battery in the trunk area?

I have been wanting to move that battery from front to back for some time.

What is the easiest running of the positive cable forward? Placed inside or along the frame?

Installing the fuel line -6an? Outside of frame in inside of frame?

Projects for this spring that are approved via NHRA or IHRA.

I ran the battery cable inside, under the back seat and through the black plastic thing that runs along the floor on the passenger side. I used the firewall grommet out of a Chevy Cobalt where I punched the cable through the firewall. I'm not sure if that meets NHRA or IHRA rules, though.

Thanks for that info.
