The 300tdi I've acquired has well over 300,000km on it too. So it's a concern. Apparently there are ways to measure this internal pressure and also ways to externally adjust the regulator.

The VW Tdi guys have all the inside information (literally) on these pumps. Many are even using 300tdi pumps to convert VW tdi engines to mechanical injection.
