I think the biggest concern is winter driving really

Any Offroad occurrences that get to the corner of the frame and under side of the bed is a frame killer anyway
 
I guess that the rogue stick, or branch could be a concern. What part of winter driving is your concern? The mag chloride or ice buildup on the lines?
I suppose that sand getting thrown up a lot could get to them.
 
I has done it on a Jeep and on a Nissan truggy thing I helped with. I used electrical conduit with tabs to protect them. Tabs bolted to the frame. There were some small sections left unprotected but it wasn't much.

I have a bunch of rubber coated P clamps
 
You are going to a ep381 pump right? So your pressure for the EFI will be 55-65 psi right? It's going to have a lot more resistance to boil fuel in the line than the 15psi run with the tbi based systems.

I know I had my fight with heat and fuel that's been well documented, but after all the discussion mine turned out to be the kinked feed hose in the tank. What I'm getting to is once that was addressed I've yet to have a fuel related problem due to heat at all. That's with the lines in the stock location inside the rail with true duals. Even in 113° heat shutting the truck off and restarting without any issues.

There are pros and cons going each way for sure but I've found at least in my case the stock setup works with my exhaust being fairly tight on the pass side rail.
 
I am not seeing anyone post reasons why the lines should stay inside the frame.
And as far as heat in the fuel system, I believe that it's well known that it isn't good to heat up the tank and lines. And if the lines are getting baked, eventually the gas in the tank gets hot.
So what are the cons to this idea? This isn't a "factory " truck anymore, so these other factors need to be thought out. Correct?
Besides, just cuz the factory did it, doesn't make it the gospel.

Outside of the protection the frame provides there isn't anything saying he can't put it outside the rail. I just posted what I found on mine because while I originally thought the exhaust was an issue I proved it not to be.

The issue I see doing it on the outside of the rail is you don't have a clear path to run. All the body mount brackets are in the way. So one can't just make a straight run of pipe or hose without running below the mounts, which could expose it more to possible damage.

I have to look again but I think he can run it right at the top just above the body mounts.
Or if he has at least a 1" body lift he can run on top of the frame
 
The factory ran all the rear air and heaters on the outside of the frame. They were metal for the most part and they still use this method.
 
I ran -8 aluminum fuel lines on the outside of the frame on my old K10 for the last 2-3 years I had it with no issues. I’m not in a rocky environment like you but between monthly mud bogs it was frequently wheeled in a local swamp with lots of brush, sticks, etc that never bothered any of it.

The swamp was in coastal Florida so the mud / water was pretty salty, it never seemed to bother the aluminum lines.
 
I'll get a pic. I think my c30 has factory installed fuel line down the outside of pass frame coming from a single saddle tank on the driver side.
 
I didn't get any pics cuz I didn't have my phone on me but the fuel line on my C30 comes across the rear cab cross member from driver side tank then up the inside of the pass rail to where the front of the pass saddle tank would normally be and then it comes over the top of the rail and has a short rubber hose then goes steel line along the top outside of the rail over the cab mount and up to the fuel pump area. It's like a single 3/8" i.d line. Then I have a loop of rubber hose with an inline filter and it connects to the pump. It runs right at the top of the outside of the frame rail and has a few p-clamps holding it along the way.
 
I don't see an issue running the lines on the outside of the frame, I would just keep them toward the top of the frame obviously. You could build some protection later if you felt it's necessary.

Remember me questioning your dual exhaust decision? :whistle:
