Misfuel risk Moderate
US Montero Sport was gasoline-only. Primary risk is diesel added at the pump. Remaining US fleet is aging; tank corrosion can complicate drain procedures.
If the engine was not started
Keep ignition off; drain tank before any crank attempt.
If the engine was started
If run on diesel-contaminated gasoline, inspect filters, lines, and injectors; catalytic converter damage possible — diagnose per OEM.
Access procedure
- Do not start the engine. Disconnect the battery negative cable.
- Relieve fuel pressure per Mitsubishi service manual (if fuel rail pressurized on your model year).
- Support the fuel tank with a transmission jack; remove skid plate if equipped.
- Disconnect filler neck and EVAP lines per manual; disconnect fuel supply/return lines.
- Lower the tank and drain using approved recovery equipment.
- Inspect pump module and tank interior; replace fuel filter if contaminated fuel reached the line.
- Reinstall and prime before supervised start per OEM.
Notes
- Global name Pajero Sport; US market name Montero Sport on older inventory.
