would it be better if I made sure to protect the hose with with something? I'm planning on running it through a tube of insulating heat reflecting casing. I've got some around my trans lines and it looks like it would protect the line from debris damage.

The hose I'm running now is just the standard stuff from autozone. It's the same stuff they sell for new cars so I think it should be rated for modern ethanol blended fuels, bit I will double check.

And what about a braided fuel line, would that be better?
