Dan, high boost is more useful than engine prime.  I had an engine fuel pump
failure at 400 feet after takeoff from Port Columbus, OH, westbound towards
city center.  The engine immediately quit.  I selected high boost and it
immediately started.  The engine-driven pump failure was confirmed by the
Continental dealer who did the repair work.  The boost pump did its job,
IMHO.
