So I was well aware of the warnings not to run my ARB air line "too close" to the exhaust, but I couldn't really find any really good guidance about what that meant (half an inch? four inches? a foot?) so I ran my rear locker line down the drivers side frame rail anyway. I even thought I would be clever and apply some thermal tape near where the obviously close and hot bulb came closest to the line (ends are peeling but tape is intact):



Well, that part actually worked out okay, but after a day of running in the desert this past week, I had my line blow out just slightly downstream near the crossmember where the two pipes merge. At this point, the line is a little over four inches from the pipe. It's a little out of focus, but you can see the blowout a couple inches up from where I'm pulling the line into view:



I'll be replacing with some steel braided line, since it just seems a lot more robust overall, but I just figured I'd throw this out there to save others the hassle, since a similar search turned up nothing for me.

 

Thanks! That's good info to have in the hip pocket.

 

That's good to know for later one when the rear gets put in

 

I've been trying to come up with something cheap I can run mine inside of so that I don't have to worry about heat or impact. I looked a little and think I might be able to go down the inside of the frame. It will be a PITA to run, but should be well protected...

 

Humm... yes good to know this, I will be sure to keep an eye on any good ideas running this line back to the rear axle...

I had ambitions to put in the line this weekend, I am glad i decided to wait... that means i will not have rear lockers for Moab this coming week... drat..
