[Healeys] Why carry spares

[richard mayor]

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.
