I appreciate the reply,

I think I can't get everything I want, it's one or the other.

For ease of insulation and cost it's probably going to be best to get a external fuel cell and mounted in the bed on top since my new exhaust runs between the frames straight out the back and they are in the way. The only other answer I came up with is cut my exhaust and turn it to come out behind both rear wheels freeing up the area between the frame back there for a tank, but I really don't like the idea of cutting brand new exhaust off..

And an exterior fuel pump is probably going to be best in this case and maybe a future upgrade can be done.

I would like the tank behind the seat but I need the high pressure system and not sure how to rig up a return line to it. And as you pointed out I don't want it pump right behind my seat listening to that the whole time.
