Just dumping the heat into the fuel tank half the problem. You need a way to move that heat back to the engine just before starting, but not too much as your fuel will get too cold.
Plus your heat capacity will vary with the amount of fuel onboard.
Plus diesel shouldn't get too warm, I think 55°C (130°F) is the limit. That's why turbodiesels have a radiator on the fuel line returning to the tank.
