This is the genuine Bosch 0440008182, a new mechanical fuel supply pump. It replaces Cummins 4019590, which Cummins calls a fuel transfer pump. It is the low-pressure pump that pulls fuel from the tank and feeds the injection pump. It is a new part, not a rebuild, and no core is needed.

A worn supply pump shows up as hard starting, loss of power under load, air in the fuel or an engine that dies and restarts after priming. Rule out a plugged filter, a cracked pickup line and loose connections first, because they cause the same complaints. Cummins used several look-alike Bosch supply pumps on its mechanical engines, so order by the Cummins or Bosch number, not by looks.
