This will ensure that your fuel reaches something close to the temps of the coolant, at least, which is a huge increase from the ambient temp that it is when it's being pushed through the lines.

Heating the fuel rail may not be good enough, since the fuel is only actually there for a very short time... it may not be long enough for heat transfer to actually occur, whereas in a larger apparatus, such as a transmission cooler, heatsoak will be more likely to occur.

Don't forget to take in to account if the fuel system has a return or not ( most fi cars do) in which case you are flowing much much more fuel than the engine is using.
