My SD has 320k and its on its second pump, original started weeping around 215k...current pump has been great (Laso I think).

Replaced one on my dad's SD when we swapped in the engine as we had a pump on the shelf.....other than that, no failures ever, in hundreds of thousands of miles/several cars.

Pretty sure the pump on my dad's V8 is original with 308k on it..... my OM601 has an original pump with 245k or so on it....
