11700423 Injection Pump | Genuine Volvo Penta Part

🔧 Product Description

This is a genuine Volvo Penta injection pump from the fuel system group, supplied in the Stage 1 emissions configuration. It delivers precisely metered, high-pressure fuel to the injector at the correct point in the combustion cycle, making it a core determinant of power delivery, fuel economy and exhaust emissions. The Stage 1 designation distinguishes this unit from otherwise similar pumps built to different emission stages, so it must be matched to the engine's emissions specification.

🔌 Function

The injection pump pressurises diesel fuel and delivers an accurately metered charge to the injector at the precise moment required for combustion. Its metering and timing accuracy directly govern engine output, running smoothness and emissions compliance.

⚠️ Common Signs of Failure

• Hard starting or extended cranking, particularly when cold
• Rough running, misfire or uneven idle from inaccurate fuel metering
• Loss of power, poor throttle response or inability to reach rated load
• Excessive black or white exhaust smoke indicating incorrect delivery or timing
• External fuel leakage or a drop in fuel rail pressure from internal wear

🛠️ 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
