If would leak if the rig is on its rear/ tailgate.
If it were mine I would route like this.
From the tank to the passenger c pillar/ belt line node (near the clamp) then forward up the belt line tube to the harness bar, then turn to the drivers side to the drivers belt line tube, then back to the driver c pillar node then turn down and go a few inches below the floor in the corner by the ratchet. The hose would be clamped, tied whatever on the inside of the belt line and would not get hit by rocks and look clean
Long story short around the tank up high down through the floor.
