I would remove anything fuel/wise away from the motor,as far as posible away from heat.You can also use insulation on fuel line to keep from getting hot.I use that tube stuff you put on water pipes in your basement.
RE: movingb stuff away from motor...Pretty much right now, that is the case.....the fuel line is running up thru the stock location.....any other routing would put stuff closer to heat sources.....
The hose going from the regulator to the carb feels hot at some point, but have pulled the line from the c arb when it is doing this and the gas that comes out feels cool......the rest of the lines etc dont feel too hot at all.
