A vapor fuel injection system including an air pump having dedicated air cylinders assigned to individual engine cylinders and adapted to produce timed charges of pre-heated air adapted to push timed charges of fuel through a heat exchanger where the timed charges of fuel are converted into metered charges of fuel vapor. The charges of fuel vapor are subsequently pushed into and through fuel vapor delivery nozzles defined in the respective guide bodies of respective intake valve assemblies. After exiting the guide body of said valve assemblies, the timed charges of fuel vapor mix with intake manifold air and then are fed directly into the engine cylinders for combustion.
