Some diesels have fuel heaters, some are electric some are coolant warmed.
I am going to tie the cooling system into the fuel system via a heat exchanger and that will keep from having to heat the entire fuel tank.
Mainly so filters don't ice and wax up. Diesels seem to get the best fuel economy with their fuel heated from around normal temperature up to 120'F.
