The only way I"m aware of for fuel to get heat. Is when it's inside the fuel rail in the cylinder head. But I have no idea if today's systems are returnless. And if there's any other source for heat. I haven't heard about it yet.I learn something new every day.
If it also heats, can it use some of that heat to keep the fuel thawed?
My understanding is that all diesel engines have a fuel return. That's how injectors are kept cool with fuel functioning as the coolant that returns to the tank, with a secondary function being to keep fuel above the cloud point as it's constantly recirculated. This is for diesel engines as the motive power of vehicles, but in theory it should be the same for diesel engines that are APU generators or reefer generators as the need for cooling of fuel injectors there doesn't vanish just because the engines aren't powering vehicles.The only way I"m aware of for fuel to get heat.

nopeOnce a diesel engine is started and running, it's hard for fuel to gel up enough to clog injectors or a fuel filter.
You never said how cold it was in the morning in question.I know everyone says it shouldn't be a problem, but a friend went up to Big Bear without adding anything to his Duramax and it wouldn't start the next morning. I suspect gelling. I was just wondering if there was a concrete temperature when you should start adding to our summer fuel, but it sounds like you can never really be sure. Thanks.
That truck didn't have to refuel at least once somewhere along the trip? I don't know a F-250 that has the range to travel from Texas to Minnesota without needing to refuel.An F-250 at my motel 6 did gel - rookie owner had driven it north from Texas without refueling/recirculating after arrival in Rochester Minnesota.
compartmentsi drove 017 cruze stick in arctic conditions from boston to minnesota on its first winter, high temp was +16F, low temps were -16F (without wind chill).
I added no power-service/anti-gel but certainly did refuel at major truck stops and did worry about gelling on those -16F nights. An F-250 at my motel 6 did gel - rookie owner had driven it north from Texas without refueling/recirculating after arrival in Rochester Minnesota.
The only thing I wish I added to the car was BLIZZAK TIRES. Not a fuel additive .
To the previous comment that we can have no idea the actual blend of the diesel we buy, that's not entirely true. On the -16F arctic-conditions driving to/from/in minnesota, I refueled at at least one location that my eldest son had filled the diesel tank from his fuel tanker the day before or the same day - blended the diesel with additive at the refinery/terminal as he loaded it into the tanker "pockets" (i think thats maybe what he called them.)
ps - Minnesota is awesome.
