Professional Installation Required
Involves timing alignment, high-pressure line disconnection, and ECU diagnostics.
Must be performed by certified diesel technicians.
Use Genuine or Certified Rebuilt Units Only
Avoid cheap clones — they often use substandard materials and fail within months.
Choose OEM, Bosch-remanufactured, or certified aftermarket pumps.
Ensure Clean Diesel Fuel
Use high-quality diesel and change fuel filters regularly (e.g., WG99255511121).
Water and dirt are the #1 cause of HPFP failure.
Never Run Dry
Do not operate the pump without sufficient fuel supply.
Running dry causes immediate scoring and permanent internal damage.
Replace Fuel Filters Before Installation
Install a new primary and secondary filter before starting the engine.
Contaminated filters destroy new pumps.
Prime the Low-Pressure System First
Use manual primer pump or electric pre-feed pump to fill the system.
Ensures lubrication and cooling during initial startup.
Align Timing Correctly
Match timing marks on camshaft and drive gear.
Misalignment can cause severe engine damage.
Torque Fasteners to Specification
Mounting bolts
High-pressure lines
Electrical connectors
Follow manufacturer’s torque values for:
Typical range: 35–50 Nm (check service manual).
Bleed Air from Fuel System
Operate pre-feed pump until no air bubbles appear.
Failure to bleed causes hard starts and cavitation.
Perform Post-Installation Diagnostics
Read rail pressure
Clear fault codes
Confirm normal operation
Use OBD-II scanner or SINOTRUK TechTool to:
Avoid Short Trips Immediately After Start-Up
Let engine run at idle for 2–3 minutes to stabilize oil and fuel pressure.
Storage Advice
Keep sealed in anti-corrosion packaging.
Store upright in dry, room-temperature environment.
