[Healeys] fuel pump

Surely the manufacturers of the pump have addressed this question.  Has
anyone looked at the pump specification for "minimum voltage"?

Conceivably--note: 'conceivably'--less than 12V at the pump would leave the
electromagnet charged but unable to fully retract the diaphragm and open the
points (or electronic circuit) to stop current flow. You'd still have
current flowing through the electromagnet, which could overheat and, well,
fry.
