- 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 frequently overlooked. You remove the Fuel Tank Cap, top off your fuel levels, and then secure it back on with every trip to the pump, but somehow this essential component remains an afterthought.
Your Fuel Tank Cap serves a vital role in the performance of your Nissan as a whole. Obviously, it seals off your fuel tank and prevents moisture, debris, and dirt from seeping into your gasoline. But here's another thing: the Fuel Tank Cap is also a component of your Nissan's evaporative emissions system (or EVAP).
As your engine runs, your fuel heats up significantly and emits toxic vapors. But, with the help of the Fuel Tank Cap, your Nissan's EVAP system helps capture and recirculate those emissions to stop them from seeping out and contaminating the surrounding atmosphere.
If you aren't able to click your Fuel Tank Cap into its opening, or if it becomes loose after you've already tightened it, you likely have an old or damaged cap. Since this component is also part of the EVAP system in your Nissan, your dashboard engine light may turn on if your cap is faulty. Other indicators of an old Fuel Tank Cap include strong gasoline odors while you drive and decreased fuel efficiency without having changed any of your travel habits.
There are several consequences of a Fuel Tank Cap that's no longer functioning correctly. A Fuel Tank Cap that doesn't seal properly can release dangerous fumes into the environment, and it could also cause costly wear and tear inside your Nissan and its engine. A broken Fuel Tank Cap can reduce your Nissan's engine performance, tank your gas mileage (no pun intended!), and cause fuel leaks. It's wise to replace your Fuel Tank Cap immediately once you notice that it is no longer functioning correctly.
Replacing a damaged Fuel Tank Cap is fast and easy, and you can do it at home. You just need to shop genuine Nissan parts online to get a seamless fit for your vehicle.
