Kees,
Hi....surely VERY useful to fit a diode? In my own, purely personal, opinion
I'd regard it as an essential step.
Once the thing's apart, it must be a shame not to fit one?? After points are
set correctly, sparking is the thing that gets them in the end?? Anything to
slow down the process....

I think it is more a question of regular maintainance, but new points may be
substandard like distributor contact points. Although I have not fitted new
points yet, I do have some NOS original SU items, not the replica ones which
may or may not be OK. Whenever I can lay my hands on NOS original items I
get them, directly needed or not.
Regular maintainance and repairing parts apparently is not a US thing,
however here in Europe, and certainly the UK, we are quite used to it so we
may clean the points now and then, which helps to keep them alive and
prevent serious spark erosion.
Once you have to tap the pump to get it going again for the first time you
have to take action asap.
The classic SU fuel pump with points is one of the most durable pumps in
existence if properly maintained and always repairable, no modern fuel pump
comes near.
It may be useful to fit a diode to reduce sparking.
