Fuel Cooler, fuel direct to Radiator?

[Bohica]

Instead of having the fuel cooler coolant go through the bottom part of the radiator. Could you run the fuel through the radiator and remove the fuel cooler and coolant pipes? or is the lower part of the radiator not physically separated? If it isn't, manual vehicles could use the autotrans cooler to cool the fuel.
I know I'll find out why this isn't done ;)

Running fuel directly to the radiator at pressures up to 60psi + would require a ATF type cooler, radiator designed for 20psi.

The D2a radiator is single circuit (not separated) for the EU3 engine with egr cooler.

Someone here has fitted an aircooled ATF type cooler, didnt hear any feed back from.

The fuel should be maintained at 82 degC so air cooled could be overkill.

The pic is my understanding of the fuel cooler.

That 82 opening thermostat is to stop the cooler to operate in cold climates not to keep the fuel at that temp cos there's a limitation in the fuel map which works with the FT sensor inputs, as fuel temp increases the ECU limits the max amount of fuel which can be injected as from 50 to 70 degrees its limited to 43cc. at 71 degrees it drops to 41cc then it drops with every degree increase.... the colder the fuel is the better the engine will run so IMO any additional cooling for the fuel is good, also the best is to not let the tank below half when it's hot outside to keep the fuel as cold as possible
