NISSAN 17221-VB006 Fuel Filler Tube Assembly

The genuine OEM Nissan fuel filler neck tube assembly (TUBE ASSY) with part number 17221-VB006 is a critical structural component of the fuel supply system. This component provides a direct, hermetically sealed connection between the external fuel filler opening and the fuel tank. Its design ensures the unobstructed flow of fuel during refueling, while integrated vent lines allow for the controlled equalization of vapors and overpressure generated inside the tank.

Technical Characteristics and Function:

• Part Type: Fuel Filler Tube / Filler Neck Assembly (Tube Assy - Fuel Filler)
• Manufacturer: Nissan (OEM)
• Replacement / Alternative Reference Numbers: 17221VB005, 17221-VB005
• Function: Guides fuel into the tank and maintains evaporative emission (EVAP) system integrity.
• Typical Failure Symptoms: Due to their exposure near the wheel arch, metal pipes are prone to external surface corrosion and perforation from road debris, mud, and de-icing road salts. A perforated tube can lead to fuel leakage, a strong odor of gasoline or diesel, difficulty when refueling, and Check Engine trouble codes caused by EVAP system pressure leaks.
