Fuel Lines to Generator

This is a warning to anyone (like me) who installed an Onan generator in the pre-wired generator compartment of your XLR 27HFS toy hauler. Not sure if any of the other XLR toyhaulers are like mine.

Take the bed mattress off and swing the hinged plywood piece over the generator compartment open (this is from inside the trailer). Look at where the two (black) gas lines go from the generator compartment through the floor. There is likely a mass of foam there to cover the hole where those lines and the major wiring passes through to underneath.

If yours is like mine, the gas lines are actually touching the (metal) generator comparment. Want to take a wild guess what part of the generator is on the other side of that metal? The muffler. Brilliant.

I just happened to be applying soundproofing material to the generator compartment yesterday while running the generator and my hand touched the metal wall of the compartment. It was hot enough to burn my hand, so I'm guessing it is also hot enough to melt the gas lines - or boil the gas in those lines. Either scenario leads to disaster.

So I broke the foam out of the hole, pulled the gas lines as far away from the generator comparment as I could, applied 3 layers of soundproofing (which has aluminum on one side) to the side of the generator compartment, and wrapped another layer (aluminum facing out) around the hoses themselves where they were near that corner.
