Be careful trying to heat the fuel with a mechanical injection pump. Heating the fuel makes it more compressible which effects injection timing.

The best way to get a higher efficiency with a diesel is to cram more air into the cylinders. This allows more fuel energy to go into heating the combustion gasses and less heat transferred to the engine block. Cooler intake air also helps for the same reason.
