Genuine Jaguar NJD5942BB Fuel Tank Cap / Gas Cap OEM Replacement

The Genuine Jaguar NJD5942BB is an OEM fuel tank cap (also commonly referred to as a gas cap or fuel filler cap) designed as a direct factory replacement for compatible Jaguar vehicles. Sourced directly from Jaguar, this cap ensures a precise, manufacturer-specified fit and seal — no modifications or adaptation required.

Key Features:

• Genuine OEM Part — manufactured to original Jaguar factory specifications for guaranteed fitment and performance
• Proper Fuel System Sealing — prevents fuel vapors from escaping the tank and blocks moisture and contaminants from entering
• Emissions Compliance — maintains the integrity of your vehicle's evaporative emissions (EVAP) system; a faulty or missing fuel cap is a common cause of check engine light illumination and failed emissions inspections
• Direct Replacement — installs without modification; replaces worn, cracked, or lost original caps
• OEM Part Number: NJD5942BB
• Supersedes / Cross-Reference: NNA5942AA

A properly functioning fuel cap is a critical component of your vehicle's fuel and emissions system. When a cap fails or goes missing, it can trigger the check engine light, cause fuel evaporation loss, and result in a failed emissions test. Replacing it with a genuine OEM Jaguar part ensures your vehicle continues to operate as designed.
