I have a safety related question here. Since I've switched to longtubes my fuel lines for the external tank pump (which are steel braided) are VERY close to me headers. The closer of the two lines is the return line and it's about 1/2" away from the header. The send line is about 1" away.

Is this dangerous? I understand that if there was a leak a fire could start really easy but without a leak am I at risk for boiling the fuel , especially when the car is shut down and restarted? At what temps will fuel boil and what happens internally when the boiling fuel reaches the injectors?
