Product Details

Motorad Tethered MGC4854T is a direct-fit style fuel tank cap for a wide range of Toyota, Lexus, Hyundai, Kia, and Mazda vehicles. The tethered layout helps keep the cap attached to the vehicle during refueling, while the vented construction and relief-valve design are intended to maintain proper tank pressure and reduce evaporative fuel loss. A worn or leaking cap can contribute to fuel odor, evaporative emissions faults, and unnecessary fuel loss over time. This part cross-references 9MGC4854T and 4854BT for the same application.

What This Fuel Cap Helps Address

• Fuel vapor leakage from a worn or damaged cap seal
• Check engine light concerns related to evaporative emissions faults
• Fuel odor around the vehicle or fuel filler area
• Loose, missing, or damaged tethered fuel cap assemblies
• Pressure retention issues in the fuel tank system
