fuel line heat shielding?

[evilokc]

I'm having some fuel issues. I'm trying to address these issues from all angles. I grabbed the fuel line last night after the truck had been running for and 45 minutes and it was very hot. before that it hadn't occurred to me that there might be a heat issue. they do run only a few inches from a header. what kind of heat shielding are you guys using? I know they make wrap and I'm at least going to use that but I'm toying with the idea of making an actual metal shield as well. thoughts?
