MotoRad MGC-502 Locking Fuel Cap for Ford F-250/F-350 Super Duty and E-Series

Secure, OEM-Quality Fuel Cap for Ford F-250 F-350 and E-Series Vans

The MotoRad MGC-502 locking fuel cap brings a tangible sense of security to every fill-up by deterring vandalism and fuel theft. Crafted with OEM quality materials and built to meet safety standards, this cap delivers a sturdy, precise fit that complements your vehicle’s fuel system. In addition to security, the cap is designed to pass state and federal emissions requirements, helping you stay compliant with minimal fuss.

Key design elements focus on controlling fuel evaporation while maintaining proper venting as temperatures shift. The unit includes a dedicated pressure and vacuum relief system to manage vapor inside the tank. A leaking fuel cap can allow substantial evaporative losses over a year, so a well-sealed cap like the MGC-502 offers a practical, maintenance-friendly safeguard for daily driving and longer trips.
