Gates 05-12 Ford Expedition OE Equivalent Fuel Cap

This is the Gates OE Equivalent Fuel Cap, part number 31841. It's designed to replace the original cap on a wide range of Ford, Lincoln, and Mazda vehicles, including models like the Ford Expedition, Ford F-150, and Lincoln Navigator. A properly sealing fuel cap is crucial for your vehicle's emissions system and fuel efficiency, preventing fuel vapors from escaping and ensuring the evaporative emission control system works as intended.

This cap is built to meet the original equipment specifications, meaning it should fit right and seal effectively, just like the one that came from the factory. When you're replacing a fuel cap, you're often doing it because the check engine light came on, and a faulty cap is a common culprit. Installing a new, well-built cap can often resolve that issue and get your vehicle running cleanly again.
