Yes my UBP did 20k miles on its own that I was aware of, and probably a fair few miles more that I didn't know about.
It was your quote here that maybe I misunderstood:
[Quote] Diesels with two electric pumps (ITP and UBP) may under certain conditions fail to get sufficient fuel if one fails. The ITP has adequate delivery capacity when assisted by the UBP. So, when it has to work alone, it needs to do the work of the UBP as well. Whether it copes with the load depends very much on the lift it has to cope with. [QUOTE]
