- Seals off your fuel tank and prevents contaminants in your gas supply
- Plays an important role in the EVAP system
- Easy to replace on your own
The Fuel Tank Cap on your Nissan is often neglected. You twist off the Fuel Tank Cap, fill up your tank, then secure it in place again with every trip to the pump, but somehow this essential component remains an afterthought.
Your Fuel Tank Cap has a big part in the performance of your Nissan as a whole. You already know that it provides a seal for your fuel tank and stops debris, moisture, and dirt particles from contaminating your gas supply. But, it has another purpose, too. The Fuel Tank Cap is an integral part of your Nissan's evaporative emissions system (or EVAP).
As your engine runs, your fuel heats up significantly and emits harmful fumes. But, with the Fuel Tank Cap in place, your EVAP system can safely contain and recirculate those emissions to stop them from seeping out and contaminating the atmosphere.
If you aren't able to click your Fuel Tank Cap into place, or if it loosens on its own even after you've tightened it completely, you're likely dealing with an old or damaged cap. Because the cap is part of your engine's overall EVAP system, your dashboard engine light may turn on if your gas cap is malfunctioning. Other signs of a worn out Fuel Tank Cap can include strong gasoline odors while you drive and decreased fuel efficiency with no significant change in your travel behaviors.
There are several consequences of a Fuel Tank Cap that's no longer functioning correctly. A Fuel Tank Cap that doesn't seal properly may release harmful emissions into the environment, and it could also create costly wear and tear in your Nissan. A worn out Fuel Tank Cap can decrease engine performance, lead to poor gas mileage, and cause fuel leaks. Replace your Nissan Fuel Tank Cap immediately once you notice that it isn't sealing or tightening properly.
Replacing your Fuel Tank Cap is fast and easy, and you can do it at home. Just be sure to shop genuine Nissan parts online to get the best possible fit.
