- 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
Your Nissan's Fuel Tank Cap is a car part that is often neglected. You twist off the Fuel Tank Cap, fill your vehicle's fuel tank, then secure it in place again with every trip to the pump, but that's probably the only time you think to acknowledge your fuel cap.
Your Fuel Tank Cap has an important purpose in the performance of your Nissan as a whole. For starters, it provides a seal for your fuel tank and prevents moisture, debris, and dirt from seeping into your fuel. But, it has another purpose, too. The Fuel Tank Cap is also a component of the evaporative emissions system (aka EVAP) in your Nissan.
As your engine runs, the fuel in your vehicle heats up and generates dangerous byproducts. Fortunately, with a properly working Fuel Tank Cap, the EVAP system can safely contain these exhaust gases to prevent them from being released into the air around your vehicle.
If your Fuel Tank Cap doesn't make clicking sounds when it screws into place, or if it becomes loose after being tightened, you probably have an old or damaged cap. Since this part is a component in your engine's overall EVAP system, your dashboard engine light may turn on if the fuel tank cap is faulty. Additional signals of an old Fuel Tank Cap include gasoline odors while the engine is running and decreased fuel efficiency (with no change in your driving habits).
Consider the drawbacks of a Fuel Tank Cap that's no longer functioning correctly. A Fuel Tank Cap with a busted seal may push damaging byproducts into the air around your Nissan, but it may also cause a domino effect of other issues inside your Nissan and its engine. A failing Fuel Tank Cap can diminish engine performance, tank your gas mileage (no pun intended!), and create messy fuel leaks. You should consider replacing the Fuel Tank Cap in your Nissan as soon as you realize that it is not operating as it should.
Replacing a damaged Fuel Tank Cap is simple, and you don't need special tools to do it. You just need to shop directly with Nissan Genuine Parts to get a seamless fit for your vehicle.
