OEM Fuel Injector O-Ring - Larger for 1996-2002 Nissan Pathfinder models equipped with the VG33E powertrain. 

The Fuel Injector O-Ring - Larger seals the fuel injector to the fuel rail and intake manifold. 

Here are some signs that the Fuel Injector O-Ring - Larger may need to be replaced:

• Fuel leaks: If the fuel injector O-ring becomes worn or damaged, it can cause fuel to leak out of the fuel injector. This can result in poor fuel efficiency and can also be a fire hazard.
• Rough idling: A worn or damaged fuel injector O-ring can cause air to leak into the intake manifold, which can cause the engine to run roughly or idle erratically.
• Misfires: If the fuel injector O-ring becomes worn or damaged, it can cause the fuel injector to spray fuel into the combustion chamber unevenly, which can cause engine misfires.
• Poor fuel efficiency: If the fuel injector O-ring is leaking, it can cause the engine to run too rich, which can result in poor fuel efficiency.

Replace your insufficient O-Ring - Larger with this genuine Nissan replacement.

Please refer to the diagram provided to verify part placement. (This is the larger O-Ring of the two that attach to the Fuel Injector)
