Rebuilt pumps are pumps whose worn parts have been replaced and which have been set on a test bench to the original values. Before a new or rebuilt pump is fitted, the cause of the old pump's failure must be understood: if it failed through water, dirt or running dry, the fuel system is cleaned and the tank and lines are drained and flushed. The pump is lubricated by fuel, not engine oil, so fuel quality and regular filter changes directly decide its life. Water is drained from the bottom of the tank regularly. The label on the pump is kept, as it is used to confirm the part number.
