Routing ARB compressor air line

[Herculean T4R]

I recently installed rear ARB locker. This weekend I will be installing ARB compressor in the engine bay on the passenger side. Looking for suggestions on how to route the air line from the engine bay to the rear axle.
thanks!

I would just run it down the frame (maybe inside the frame?) all the way down and secure it with zip ties and leave plenty of slack at the end for axle travel. I'm about to undergo this too, but My compressor is in my cargo area and I'm doing front and rear lockers, so I'm trying to decide if I want to run the line down the frame to the front or keep the line inside the cab and go through the firewall

That's how I did mine. Follow frame. Up and over muffler heat shield,along upper link lots of slack to locker nipple.

I followed the fuel lines all the way into the engine bay and every where I thought it might rub or need extra protection I put transmission line over the air line. The air line fits perfectly in the transmission hose and protects it really well.
