To me it wouldn't be an MG without the clicks <G>.
It is true the old sparkys were not the best engineering. But the newer
designs with proper flyback diodes are much better. And the most recent
units with SS switching are even more reliable.
Aside from the points/switching, even the oldest SU pumps perform quite
well and live long.
But again, who could really enjoy driving an MG without carrying the
requisite on board hammer <G>.

Fully agree on this - I dislike the ever sparking contact design in this
pump very much as well.
As an electrical engineer (study) this sort of Micky Mouse solution looks to
me as very unprofessional - I like the engine driven based fuel pump much
better.
My wife had a Chrysler Horizon for over 13 years and this mechanical pump on
the engine always worked flawlessly, provided the filter was cleaned now and
then. Please don't start the Chrysler cannot be compared with an MG - the
French guys (the car was designed by Simca!) sometimes really have made some
well thought over designs!
Think about the Citroen hydraulic suspension and the world's first monocoque
(Traction Avant).
Cheers,
Hans

On the topic of fuel pumps I have been wondering why MG used electrical
pumps on their cars. My fathers 70 Land Rover 88 has a mechanical pump
which seems to work flawlessly. Is this a cost issue or just a unique
"feature" of MG's?
