WARNING
• Fuel is highly flammable. Do not handle it near flames or heat.
• Spilled fuel may catch fire and therefore, must be wiped off completely.
CAUTION
• Any contamination of the supply pump, even if it is minor, will greatly affect the performance of the en-
gine. After removing pipes, hoses, or other parts, plug the openings with covers. Wash eyebolts and new
gaskets in light oil and keep them away from contaminants.
• Contact Bosch Service Station for any service needs of the supply pump.
Installation sequence
Follow the removal sequence in reverse.
CAUTION
• Make sure that the harness (marked with “ ”) of MPROP (rail pressure control valve) is connected to the
supply pump before starting the engine. Starting the engine without connection causes a malfunction.
