Here is some line I am contemplating using on the new fuel system...

This will not conduct electricity (made from nylon filament) and is burst proof to atleast 250 psi. I have some in my garage from my race car and it is nice stuff. This should be acceptable, but I am not sure about the burn factor.... but I am no expert. LOL
I am gonna go outside and cut a peice and try to burn it and I will report back. I don't think it will burn real easily though... I'll be back with news.
