Choosing A Fuel Tank Filler Cap

A fuel tank filler cap closes the filler neck on a vehicle designed to use a removable cap. Match the vehicle, fuel system and part number, including any engine or build-date limits in the listing. A cap with a similar diameter or thread is not necessarily designed for the same sealing and pressure requirements.

A-Premium offers caps for selected gasoline and diesel vehicles. Some include a tether, and certain locking versions come with keys. Choose the configuration specified for the vehicle rather than treating gasoline and diesel caps as universal replacements.

Fuel Cap Sealing And Emissions

On vehicles with a capped gasoline filler and an evaporative-emissions system, the cap helps seal the filler opening so fuel vapor is contained within the system. A loose or damaged seal can contribute to a warning, although a vapor leak can also occur elsewhere.

Check that the cap is properly seated and inspect the seal and filler neck for damage or contamination. Follow the vehicle's installation instructions; some caps are designed to click when tightened.

Frequently Asked Questions (FAQ)

Can a loose fuel cap turn on the check engine light?

On some vehicles, an improperly closed or leaking cap can be detected as an evaporative-system leak and trigger a warning. Other leaks or components can produce similar codes, so continue diagnosis if securing the cap does not resolve the condition.

Will a locking gas cap include keys?

Some A-Premium locking caps explicitly include two keys. The supplied items differ by product, so check the individual description before ordering a locking cap.

Is the fuel filler cap the same as the fuel door?

The cap closes the filler neck; the exterior fuel door covers the refueling area. Some vehicles use a capless filler behind that door, so confirm the installed system before buying a removable cap.

Does every replacement fuel cap include a tether?

Tether inclusion varies. Some A-Premium products specifically list a tether, while other cap descriptions do not establish one. Check the selected package if the existing cap is attached to the filler area.

Can gasoline and diesel filler caps be interchanged?

Choose a cap specified for the vehicle and fuel system. Gasoline and diesel applications can have different filler and pressure-control requirements, and a similar-looking cap alone does not establish a correct seal.
