**5. Installation Guide**
Tools Required: Torque wrench (8–12 Nm), fuel line disconnect tool, OBD-II scanner.
Steps:
1. Depressurize the System:
• Disconnect the battery and relieve fuel pressure via the fuel rail valve.
2. Remove the Fuel Tank:
• Safely drain the tank and detach electrical connectors and fuel lines.
3. Replace the Assembly:
• Align the new pump with mounting points, torque bolts to 10 Nm, and reconnect hoses.
4. Post-Installation Test:
• Reconnect the battery, prime the system, and scan for error codes.
