I see you ran the fuel line out to the front, if you use a electric pump just run it up the fire wall and come around the back of the carbs, it keeps more heat off the fuel line.
As all the heat from the motor is blown backwards into the firewall and you say to mount the line there because it's cooler...lol.
If you'e worried about fuel temp, buy fuel cooler can and mount it to the core support or simply insulate the hard line running along the rail.
