history: get to high rpm and the pressure would drop, everyone said it is a spun bearing.

I pulled the pan and it looked like there was anti seeze all in the oil, but no real shavings, so I pulled the pump and started disecting, everything looked fine but all the edges of the pump were really rough, and the little valve next to the spring took some force to get to move.

so we put in a melling HV/ HP pump, started and and at a cold idle a get almost 80 psi and once warm 40. I hammer it and it goes back up to 80 drops a little and holds at 60ish.

I've put about 30 miles on it with the new pump and so far everything looks ok, but I'll say that I am still a little scared.

I did miss the sound of that 847 though.
