Keep ignition off; drain via access panel before the pump runs.
If the engine was started
Replace fuel filter, inspect injectors, clear DTCs, and verify fuel quality after drain.

- Disconnect the battery negative terminal.
- Access the in-tank fuel pump module via the OEM access opening (rear seat or boot panel on most NZ-new and import models).
- Disconnect electrical connector and quick-connect fuel lines; cap lines to limit vapour release.
- Remove the pump lock ring with the specified tool; lift the module carefully to avoid damaging the level sender.
- Extract contaminated fuel with approved equipment; inspect the tank interior through the opening.
- Reinstall with a new pump O-ring/gasket; reconnect lines and verify no leaks before starting.
- Prime and clear codes per Toyota repair manual; road test when fuel quality is confirmed.
