High-pressure injection pipes operate under extreme pressure. ISUZU service manuals explicitly mandate that injection pipes must be replaced with new ones whenever removed - these are single-use components.
Pre-Installation Checklist:
- Do not reuse old injection pipes - they are single-use components
- Do not bend or modify injection pipes
- Depressurize the fuel system before starting work
- Clean the area around the injector and injection pipe connections
Installation Guidelines:
- Depressurize the fuel system and disconnect the negative battery terminal
- Remove the old injection pipe from the #2 injector and injection pump
- Clean the connection surfaces thoroughly
- Install the new injection pipe with correct orientation - no bending or modification allowed
- Torque the pipe connections to manufacturer's specified torque settings
- Prime the fuel system and check for leaks
- Start the engine and inspect for fuel leaks around the connections
Maintenance Schedule:
- Inspection: During routine fuel system service or if fuel leaks/performance issues appear
- Replacement: Immediately if failure symptoms appear
- Note: High-mileage engines may benefit from replacing the full set (pipes #1-#4)
- Packaging: Neutral box, color box, or custom brand package
- Pack Quantity: 1 PC
- Net Weight: 0.3 kg
- H/S Code: 840999100
