Actually the QA at SU is now pretty good, and the point and
suppression technology is now way better than it was in the olden
days.  It is a HUGE mistake to rebuild a pump without a
suppression diode.  Point erosion is the primary cause of SU failure,
and the diode extends the life by a large factor.

Beg to differ, but there is this thing called a diaphragm that turns
into concrete after a few years.  They run about $35-40.  If you
replace diaphragm, points, diode and valves you can have an
essentially new pump but (a) you will have spent about $60 and (b) You
still have the valve seats to worry about.  I also believe firmly in
supporting the companies that are producing new stock for iron that is
at least 25 years old......  YMMV, de gustibus, etc etc.
