The reason the fuel in the tank gets hot is more a cause of the hot water 
from the engine heating the tank and fuel as it makes it way up to the front 
of the car to the radiator and then returns to the engine. Remember this 
water coming from the engine is normally around 190 -200 deg F, and when you 
just sit in traffic it gets hotter then that. The water lines running down 
both sides of the bottom of the fuel tank and enclosed between the frame 
rails and belly pan and the fuel tank act as heaters for the fuel inside the 
tank. And yes, the less fuel in the tank, the easier it is to heat.
