🔌 Function

Meters and pressurises diesel fuel for the individual cylinder injection events while maintaining the specified delivery timing and quantity. Maintain absolute cleanliness, match the pump calibration/data plate, set injection timing correctly and bleed the fuel system before start-up.

⚠️ Common Signs of Failure

• Hard starting or failure of one or more cylinders to receive fuel
• Uneven running, misfire or incorrect injection timing
• Low power, smoke or excessive fuel consumption under load
• Fuel leakage around the pump, delivery connection or plunger
• Contamination, sticking elements or calibration drift

🛠️ Service Notes

• Cleanliness decides whether the job lasts — cap every opening as soon as it is disconnected, work with clean tools, and never let dirt or water into the pump or its lines
• The pump is a calibrated assembly: do not attempt to alter internal settings on board, and have any testing or calibration done on proper equipment by a qualified shop
• Set timing and mounting by the procedure in the workshop manual for your engine, and fit new seals, gaskets and sealing washers on refitting
• Renew the fuel filters and cure the cause of any failure before running a replacement pump; contaminated or watered fuel will destroy the new one too
• Prime and bleed the system properly before cranking, and note that electronically controlled pumps may need parameters set with Volvo Penta diagnostic equipment before the engine will run correctly
