The aftermarket fuel pump I bought for my MGB (which I don't think
was made by Facet) uses solid state electronics instead of mechanical
points. You can tell because there is a big ol' TO3 power transistor
on the side of the case. This pump definetely could be damaged if you
hooked it up backwards, even breifly. I believe the documentation that
came with this pump stated this clearly. To put such a pump into a
positive earth car would required isolating the pump case from the
chassis of the car, wiring the + lead to the frame, and connecting
the pump case to the lead normally routed to the pump.
