I think that now we are getting to the real reason that you found so
much fuel in the  engine block. Indirectly caused by the leaky diaphragm
of the pressure regulator, which led to a buildup of fuel in the intake
that ignited inside that one runner and damaged that injector tip such
that it would constantly spray fuel, flooding the engine internally from
then on.
