ive thought about this before but with where the tanks are mounted and where the necks go, i believe it would either have to go down under the frame then back up on the other side. being routed around the driveshaft, or go through a large hole cut through the frame..i have yet to figure out way this would work, well of course a bodylift was put on and the bed was raised away from the frame..but i am against that...
