I'd move them. You really are just asking for trouble, and heated fuel never made anybody go faster.

As far as fuel boiling, or creating a vapor lock condition, I think you'll be okay. It's really hard to do that in a pressurized fuel system. When your pump is pulling the fuel, like a stock mechanical pump, it creates a vacuum in the line, which is very susceptable to vapor lock. But when the pump is pushing from the back, it creates high pressure in the line, which is tough to vapor lock. None the less, I'd put moving the fuel lines very high up on my priority list if I were you.

Take care,
~Chris
