Fuel line/ Is It SAFE??

In my plight to diagnose my running issues with my Generator on my 14 Fuzion FZ342 Toyhauler. I’ve found Keystone used a Rubber Fuel Line from the Tank all the way forward to the Generator. The fuel line is hung under the belly with hangers and not even run along the Frame Rail. Is this Standard? And even Safe under NHTSA?
Has anyone made their own Mods to make it safer?
The fuel line is it my running issue but I found it odd.

"Rubber" fuel line? Is it actual fuel line (it should say on the side of the line)? If so, it should be OK. Rubber fuel lines have been used in vehicles for a long time. If it's above the coroplast on the bottom it should be OK. If they used the proper hangars and attached them correctly I doubt you have an issue.

Yes it is actual Fuel Line. But it is hung below the Coroplast. There is a Fuel Line and I believe a vapor recovery line routed together. Hangers about every 2 ft

I suspect under the coroplast is the best thing. I was thinking about it getting hung on something but fuel lines on vehicles followed the frame and I suspect that is what they did with yours. In retrospect, I wouldn't want the gas line above the coroplast and then have a leak....that might be a real problem. With hangers every 2' I don't see a problem unless you just don't like it and wanted to go with stainless steel fuel line or something. If it were me, and I knew it was ran like that, I would just check it periodically to make sure it wasn't sagging or a hanger hadn't broke.

I’ve seen rubber LP lines run the frame from front to back, so I don’t see an issue with fuel lines. I would prefer any leaks be vented to atmosphere rather than confined space ( inside underbelly).

If it has a possibility of chafing on the frame or something else, you can wrap a slightly larger hose (split lengthwise) over the fuel line on the chafe point and zip tie it.
