I know there are always endless “what-ifs”
that can be asked in such a situation…but here goes…
I don’t know much about the
continental engine, (and I know we are still waiting for analysis on some
recent engine out accidents). What failure modes exist where fuel pressure
may drop but adding more fuel will make the problem worse (i.e. the boost pump
coming on automatically)? Is there something that can be done to the normally
aspirated continental IO-550 that no matter how many pumps are driving fuel to
the engine, the mixture control is still very much in charge?
Maybe I missed the post that described this?
(I don’t seem to have the ability to
let this thread die)

The Columbia
has a latching relay that kicks in whenever the fuel pressure drops below a
certain point, a really nice setup. You "arm" the pump before
takeoff. That would be nice to have at 400 AGL. In Carl La Rue's
situation, the only thing that would have happened would be an annunciator
light coming on.
