[Christ]

By the way, there was a discussion about this in another thread, but I can't remember which one it was...

I said there, and now here:

Simple way to heat your manual car's fuel would be:
Add radiator from automatic version of your car. Plumb fuel through radiator at auto-fluid line openings.

This would at least heat the fuel to whatever the coolant was. Problem with this, is pressure differential and vapor lock. Might be a problem, might not.

Also, pre-vaporized fuel can cause your engine to run lean, as your injectors are tuned for a certain fuel density.. they can only compensate so far. Just like with carbs, you'd have to jet them down if you were using pre-vaporized fuel.
