Do fuel coolers work? I mean is there any benefit in using one? I understand the colder fuel is suppose to help cool the Intake charge? Is the all just BS black magic or does this actually show performance improvements?

I doubt it would do much. maybe for rally cars that go through the deserts..

My bet would be that it would be far more productive focusing on cooling the intake air, rather than the fuel. Air seems to have a tendency to heat up quite a bit before it even enters the combustion chamber in a FI car.

While I would focus my money and efforts on cooling intake air long before fuel, it would be interesting to hear about results of cooling fuel.

If you can keep the fuel way colder, then maybe.

Maybe wrap a fuel line around the AC hardline or mount an ice tank somewhere.

Or move to Canada.

The old XJ6 Jaguars actually have a fuel cooler loop on the AC compressor line... But I think that was more of a post-design solution to fix vapor lock issues.

I'd think a fuel cooler might work best in a direct injection engine? For our batch-fired engines, where 3 of the 4 fuel squirts will puddle in the intake and against the valve, the fuel will quickly be heated up.

very good point
