Did you manage to fix the problem?

Did you the main dealer use the proper washers? I'm interested to know

I would say it is the pump itself modelwise. The 3.1 and 3.0 are completely different animals. The 3.1 almost never has leaky injectors as they aren't in a common rail.

I got mine fully refurbed and reconditioned for £125 at a diesel specialist in Norwich (when I was living there).

In fairness any diesel specialist in the area should be able to do the same. They are one of the most common automotive fuel pumps used.

You can get the timing almost spot on just by marking the pump (as well as going by the cast marks that are already on there)
