Good To Know

Q: Why is it important to have a properly sealing fuel cap? A: A secure cap prevents fuel vapors from escaping into the atmosphere and maintains the necessary pressure for the fuel pump to operate correctly.

Q: Can a loose fuel cap cause a check engine light to turn on? A: Many modern vehicles detect pressure losses in the fuel system and will trigger a diagnostic code if the cap is damaged or not tightened properly.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
