There are stories on this forum of people with updated steel plungers just like you that still suffered pump failure. It's from all these stories that a rebuild interval of about 400,000-450,000 miles was determined. Your pictures show some scuff marks which indicates there's already wear. It may not fail tomorrow, but at some point it will. Even more likely because it needs to work harder to keep the fuel pressure up because of the leak in the system.

As for the leak, if you can't find any cause in the plumbing then you'll want to start looking at the injectors.

Oh, I didn’t know this type was also that dangerous. I get what you guys mean and yeah them marks don’t give me any confidence. Plungers, rollers and gasket should do it right?
