Or, if you plumb in parallel with a DPDT switch that will enable you to
throw the switch one direction for a pump, the other direction for the other
pump and center for both to be off -- another theft security measure.

Two pumps in series might not be suitable for a racing Healey, but they have
worked just fine on my street BJ8 without any problems for a long time.
It's just simpler to plumb them in series than in parallel, in my opinion.
If you have two pumps in parallel with separate switches, then you can run
both pumps at the same time and get twice the flow rate at the same output
pressure. Running two pumps in series at the same time will provide the
same flow at double the output pressure - not good for the carbs. So, for
pumps in series there should be only one switch to prevent running both
pumps at the same time.

On my Healey racecar I ran two SU pumps in parallel with two switches.
Never had a failure. I would alternate the pumps from time to time so I
knew they were both working. It seems to me that plumbing them in series
puts needless restriction in the flow.
