3/8" air hose works good for the lines, just make sure you route it away from your exhaust. If you still have the LSPV attached, you can zip tie the hose to the arm about mid way up the arm, then run it up into the fender. I would also suggest running the line to the front of the bed, instead of the tail light, because entering and exiting a hole, the front noses down going in and the rear dips down when coming out.
