Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the battery to ensure safety during repairs.
  • Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
2. Remove Fuel Pump Access Cover
  • Locate the fuel pump access cover in the trunk or under the rear seat.
  • Remove any screws/bolts securing the cover.
  • Carefully lift the cover to expose the fuel pump assembly.
3. Disconnect Fuel Lines and Wiring
  • Use a fuel line disconnect tool to detach the fuel lines from the pump.
  • Carefully disconnect the electrical connector from the fuel pump, ensuring not to damage the wiring.
4. Remove Fuel Pump Assembly
  • Unscrew the retaining ring that secures the fuel pump assembly to the fuel tank.
