About this reconditioned pump
This is a remanufactured genuine MAN unit, not an aftermarket rebuild. It has been stripped, inspected and rebuilt to MAN's original specification with genuine parts, then calibrated and tested on a bench so that delivery quantity and timing are back to factory figures. That calibration is what matters most on a fuel pump, because injection quantity and timing set the engine's power, its fuel burn and its emissions.
Because it is factory-remanufactured, it carries the official MAN warranty of 2 years, the same as a new pump, and it is supplied on an exchange basis. A refundable core surcharge is added at purchase and returned in full once you send your old pump back, provided the core is complete and rebuildable. Your net cost is the exchange price, which is usually well below a brand-new unit.
If you would rather fit a new pump, the equivalent genuine unit is 51.11103-7846. We will quote both so you can compare.
One caution that applies to any pump, new or reconditioned. Water and dirt are what killed the old one, and they will kill this one just as quickly. Before the engine runs again, find the cause of the original failure, clean the tank, renew every fuel filter, drain the water separator and check the injectors and lines for debris.
Send us the model and serial number from your engine's data plate and we will confirm that 51.11103-9846 is the correct pump and the exact core terms before anything ships.
