Genuine Nissan 17251-3LM0B Fuel Tank Cap with Tether OEM Gas Cap

The Genuine Nissan 17251-3LM0B Fuel Tank Cap is an OEM-quality replacement gas cap designed to provide a precise, factory-fit seal for your Nissan fuel system. Manufactured to Nissan's original equipment specifications, this cap ensures reliable performance and proper integration with your vehicle's fuel and emissions systems.

Beyond simply sealing the fuel tank from outside contaminants like dirt and water, this cap plays a critical role as part of the EVAP (Evaporative Emissions Control) system. It helps contain fuel vapors that build up as the fuel temperature rises during normal driving, preventing harmful emissions from venting into the atmosphere.

Key Features:

• Genuine Nissan OEM part — manufactured to factory specifications
• Includes integrated tether to prevent cap loss during refueling
• Direct replacement for worn, cracked, or damaged fuel caps
• Supports proper EVAP system function to prevent check engine / emissions codes
• Backed by a minimum 12-month manufacturer warranty
• Replaces superseded part number 17251-3LM0A

Choosing a genuine OEM fuel cap ensures the correct fit, thread pitch, and sealing torque click — eliminating the risk of fuel odors, check engine lights, or failed emissions tests associated with ill-fitting aftermarket caps.
