Dana,
I do not know of a reason to use both pumps at the same time. My thoughts
on this subject are directed to the electrical. If you use an single switch
it may have the effect of reducing redundancy. While redundancy exists for
the pump the wiring will not be fully redundant. The CB and wiring to the
common of your switch will serve both pumps and a failure in the CB, switch,
or lead in wiring will render both pumps inoperative. My current plans call
for 2 batteries, each pump, ECU supply, Coil supply etc. from each of the
batteries.

Subject: [FlyRotary] Fuel pump question.
Man am I ever going to expose my serious lack of electrical knowledge
here:-) I'm planning on using a single pole double throw switch to
activate
one or the other fuel pump, but not both. Is there ever any reason to
have
both pumps on at the same time??
