Fuel line question

I'm building a CJ7 up with stroker and I am using a 93 YJ as a donor. I'm thinking of using the fuel lines from the YJ. My question is, should I be concerned about the fuel supply running down the same side (left frame rail) as the exhaust? Am I worried about nothing or will I have problems with vapour lock or effiency problems?

Thanks for your advice.
Dan

I would say route them down the passenger side all the way to the radiator across the front then down the drivers side. Just my opinion.

My CJ suffers from vapor lock because my fuel lines & filter are near the exhaust pipes. I'm hoping to fix it soon.

I have Thermo Tec express sleeves on the fuel line where it comes across from the passenger side over the transmission. And another one as it runs along the manifold up to the front of the fuel rail. I'd really like to run a whole new line as I described in my other post.

What I haven't insulated yet are the fuel line, filter and pump that are in front of the gas tank next to the exhaust.
