need some advice, running 3/8" fuel line, how to run, what to use

You guys know there are flexable rubber fuel lines made for fuel inj. hi/pressure and any kind of fuel now, that`s even accepted for the nhra, don`t you? All u need to do is run it away from any heat and away from anything that will explode. Nothing on the firewall either.

Yup. Inside the frame rail tucked up.
