Fuel Filler Cap - Mopar (68109840AC)

The Fuel Filler Cap - Mopar (68109840AC) is a genuine OEM sealing component designed to securely close your vehicle’s fuel filler neck and help maintain the integrity of the fuel system. Engineered to meet factory standards, this cap plays an important role in preventing fuel vapor leaks, protecting the fuel tank from contamination, and supporting proper emissions system performance.

Constructed from durable, fuel-resistant materials, this Mopar fuel filler cap is built to withstand repeated use, temperature fluctuations, moisture, and exposure to gasoline vapors. Its precision-molded sealing surfaces and locking engagement are designed to create a secure seal, helping maintain proper pressure within the fuel system while reducing the risk of vapor loss or outside debris entering the tank.

A properly functioning fuel filler cap is essential to your vehicle’s evaporative emissions system. A worn, loose, or damaged cap can trigger a check engine light, lead to evaporative emissions leaks, or allow dirt and moisture into the fuel system. Replacing it with a genuine Mopar OEM part helps restore proper sealing performance and ensures reliable compatibility with the original fuel filler assembly.

In addition to its functional role, this fuel filler cap is designed for easy everyday operation while maintaining a factory-correct fit and finish. Because it is made to Mopar’s exact specifications, it offers the dependable retention, sealing, and durability required for long-term use without the guesswork often associated with universal aftermarket caps.

Installation is simple and quick for both professional technicians and vehicle owners. Its direct replacement design allows it to install just like the original cap, making it an easy but important maintenance item for preserving fuel system integrity and emissions compliance.
