I had the heui pump go out at 42k. Limped home from death valley to LA area. I am at a few hundred shy of 80k now. Two months before the heui went out, I had it at a local dealer who changed the fuel filter. Didn't even bother to clean the mount, filter. I made a comment at the time. Some miles later the heui went out. Two versions what happened, 1 is dirt, then other is the pump shaft is too small and starts to cavitate, sending metal shards down stream to the injectors. It was fixed under warranty. I was told at the time there's an updated pump out there proving to be fine and the aftermarket has some good solutions as well. Needless tobsay, I do my own maintenance now unless time is a bother. I do know the old 7.3L powerstroke is heui and many of those less stout motors have 300, 400 k on them no pump change.
Fwiw if you find a coach you love but the number comes up with the old pump via cat, you could premptively change out the pump. Just price the change into your offer. I've heard it done for 1400-2k. Check your local shop first.
Good luck
