If I can ask, without a shutoff valve, how would you service/replace
your fuel pump (short of draining the tank)?

This really doesn't apply to planes with multiple tanks, as the fuel=20
shutoff generally does double duty as a selector.  But I have only one=20
tank, so the cutoff valve is really only useful in case of an engine=20
fire or in preperation of an emergency landing.

With a fuel pump that blocks flow when it isn't running, what useful=20
purpose does the cutoff valve serve beyond increasing pilot workload? =20
Won't cutting power to the fuel pump provide the same service and=20
eliminate several failure modes?
