Agility Autoparts Fuel Tank Filler Neck P/N:4063031
Route fuel cleanly from the cap to the tank with the Agility Auto Parts Fuel Tank Filler Neck (MPN 4063119). It installs as a direct-fit replacement for the 1998-2001 Nissan Altima with the L4-2.4L engine, restoring a secure fuel-fill path when the original neck has rusted, cracked, or begun to leak or seep at the pump.
Agility offers a complete line of fuel tank filler necks covering a wide variety of North American vehicle applications, and this unit is engineered to meet or exceed OEM specifications.
Signs the original filler neck may need replacing include a fuel smell near the rear of the vehicle, fuel seepage or staining along the neck, difficulty fueling, or a fuel-related check engine light tied to a leaking fill path. If a failed filler neck is the cause, this replaces it.
