That would be bad. Systems with return lines need the flow for cooling and fuel pressure regulating purposes (I think). It probably would not run if you blocked it off, or it would run poorly. New cars do not have return lines, so maybe something could be done there. But I wonder what hot fuel will do to the life of a fuel injector.
I would listen to mwebb - heating fuel will probably have little effect on anything.
