21103245 High-Pressure Pump | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta common-rail high-pressure fuel pump used in the TAD560VE fuel system. Driven mechanically by the engine, the pump receives filtered low-pressure diesel fuel and raises it to the pressure required by the common rail and electronically controlled injectors. Internal tolerances are extremely fine, making fuel cleanliness, correct priming and uncontaminated pipework essential.

⚙️ Key Features

• Engine-driven common-rail high-pressure fuel pump
• Meters and compresses fuel for the rail and injectors
• Precision pumping elements operate with micron-level internal clearances
• Designed for the TAD560VE electronic fuel-system pressure strategy
• Requires clean low-pressure supply, correct timing drive and approved high-pressure pipes
• Engine type: D5-series electronically controlled common-rail industrial diesel
• Quantity varies by assembly, most commonly two

🔌 Function

Generates and meters the high fuel pressure stored in the common rail so the ECU can deliver accurately timed and metered injection events across the engine operating range.

⚠️ Common Signs of Failure

• Extended cranking or no-start with low rail pressure
• Rail-pressure fault codes or derate under load
• Metal contamination found in the fuel system
• Unstable idle or engine shutdown
• Fuel leakage from the pump body, shaft seal or high-pressure connections

🛠️ Service Notes

• Treat cleanliness as the whole job: work in a clean area, cap every open line and port as it is opened, and let nothing enter the system on a cloth, a finger or a tool
• Find out why the old pump failed before fitting a new one — a pump that has worn internally sends metal through the system, and a new pump fitted into contaminated fuel and lines will fail again quickly
• Renew the fuel filters and check the low-pressure supply, tank and lines are clean and delivering properly; where contamination is found, the lines and soft hoses must be cleaned or replaced, not simply flushed through
• Fit the pump with new seals and the drive engaged, timed and tightened as the workshop manual for your engine specifies, and do not open or attempt to adjust the pump internally
• Prime and bleed the system by the manual procedure, then check for leaks — never slacken a fitting or search for a leak by hand on a running high-pressure system, as the fuel jet can penetrate skin
