Common Problems This Part Can Address

• Fuel seepage from a worn return hose

• Loose or damaged return line connections

Installation Notes and Tips

Inspect the existing return line routing before removal and compare the new hose length and connection points to the original part. Replace any damaged sealing surfaces or worn attachment points during service, and verify that the clips and fittings seat fully after installation. Because this is a rubber fuel return hose, careful handling during installation helps prevent kinks and premature wear.
