Product Details

Motorad MGC233KA is a direct replacement fuel tank cap for a wide range of domestic and import applications, including Chevrolet Silverado 2500 HD, GMC Sierra 3500 HD, Ford F-250 Super Duty, and Jeep Wrangler models listed in the fitment data. The keyed-alike design supports vehicles that use matching locks across multiple caps, while the emission-control venting helps regulate tank pressure and vacuum to reduce fuel evaporation. Motorad notes that a leaking cap can allow significant fuel loss over time, making a properly sealing replacement important for drivability and emissions compliance. This part cross-references BBB Industries 17591 for the same application.

Common Problems This Cap Can Address

• Check engine light related to fuel cap sealing faults
• Fuel vapor leakage from a worn or damaged cap seal
• Difficulty maintaining proper tank pressure or vacuum relief
• Cracked, loose, or missing locking fuel cap
• Evaporative emissions concerns on older and newer vehicles

Installation Notes and Tips

Verify neck diameter, locking style, and emissions-cap requirements before installation. This cap is intended for threaded filler neck applications shown in the fitment data, including many Chevrolet, GMC, Ford, Mazda, Nissan, and Jeep models. Clean the filler neck sealing surface before installing the cap, then tighten until fully seated and locked. If the vehicle has an existing fuel system fault code, clear and recheck after installation.
