I gave that some thought a while ago and even started playing about with Peltier cells to cool a reduced size fuel tank. I started thinking about it after learning the American drag boys habit of running the fuel line via a can with ice in it. My thinking was that fuel has a much higher thermal density than air, so if you cool the fuel it will take some heat out of the induction air which will make it more dense. Denser air lets you run more advance without detonation so you can make more power so there could be a benefit.
However :-
Not certain about the standard ECU but the one I use backs off the advance based on measured inlet temps and it would be rather challenging to get a reading after the injectors or calculate a consistent effective reduction in temps. In the grand scheme of things how much difference is a bit of slightly cooler fuel going to have compared to the heating effect of the manifold and inlet ports which will both be at least 80 or 90c. You can cool the fuel but it gets heated again in the fuel rail.

Think you'd probably get an equivalent or greater heat soak back into the fuel that has been cooled. The fuel will be in the bay/lines/injectors for a while as the 'normal' fuel flows and liters per hour of anything that isn't very high modified aren't very high.
If you did a lot of heat-proofing then you might have less heat soak. I love tinkering and fluid temp density increasing (cold air induction etc) but even I'd think the overall gain would be pretty minuscule.
