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.

With the current discussion about the recent accident, I am curious
what others have done with the fuel boost pump switch. It seems like
the options are for separate switches for high and low, a 3 way Low -
Off - High and with a 3 way with the High being momentary. I think I
am favoring the later with the thinking that the high boost is really
only needed during start for engine prime and as Skip stated this
precludes leaving the high boost on.
Other thoughts? Does this apply to the IO-550 as well?
Do any of you flying, use the high boost for anything else. In an
emergency would you use high or low boost or try both?
I am doing a IO-550 in a Legacy.
