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.
