About the remanufacturing process:

Each pump is completely disassembled and cleaned prior to the inspection process. Once the components have been prepped for inspection, the Bosch Certified Technician carefully evaluated each component to determine usability using various types of measurement equipment and machines. All rejected components are replaced with only genuine Bosch replacement components. The injection pump is then carefully reassembled according to Bosch’s procedure and specifications. One assembly is complete, each pump is then calibrated to the Bosch provided delivery specifications to ensure it’s doing exactly what it’s designed to do
