Understanding the Importance of a Fuel Tank Cap Seal

When I first learned about the fuel tank cap seal, I didn’t realize how crucial it was for my vehicle’s performance. The seal is responsible for preventing fuel evaporation and keeping contaminants out of the tank. A worn or damaged seal can lead to fuel leaks, poor engine performance, and increased emissions.
