Common Issues This Part May Address

• Hard starting caused by weak fuel delivery
• Engine hesitation from low fuel pressure
• Stalling related to inconsistent pump output
• Poor acceleration from inadequate fuel supply
• Fuel system performance loss on affected Pathfinder and QX4 models

Installation Notes and Tips

Verify exact vehicle fitment by year and model before installation. For the 2000 INFINITI QX4, confirm the vehicle was built from January 2000 onward. The included strainer should be installed where applicable, since failure to install a new fuel strainer will void warranty coverage.
