**5. Installation Guidelines** 
Tools Required: Torque wrench (8–12 Nm), fuel line disconnect tool, multimeter, fire extinguisher. 

Steps: 
1. Depressurize the Fuel System: 
   • Remove the fuel pump relay and run the engine until it stalls to prevent spills. 

2. Access the Fuel Tank: 
   • For in-tank pumps, remove the rear seat cushion or trunk access panel. 

3. Replace the Assembly: 
   • Disconnect electrical connectors and fuel lines, then unbolt the old pump. Install the 31110-G6100, ensuring O-rings are lubricated with silicone grease. 

4. Post-Installation Check: 
   • Test for leaks by cycling the ignition and verify fuel pressure with a gauge (target: 3.5 BAR).

**6. Maintenance Recommendations** 
• Inspection Interval: 

  • Check fuel lines and seals every 30,000 km for wear or corrosion. 

  • Replace the in-tank filter every 60,000 km. 

• Failure Symptoms: 

  • Engine Hesitation: Caused by inconsistent fuel pressure due to worn bearings. 

  • Fuel Odors: Indicates degraded seals or loose connections. 

• Cleaning Protocol: Use ethanol-compatible cleaners to dissolve varnish buildup in the tank.
