- 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 frequently overlooked. You twist off the Fuel Tank Cap, fill your vehicle's fuel tank, and then tighten it back into place each time you fuel up, but somehow this essential component remains an afterthought.
Your Fuel Tank Cap serves a vital role in the efficiency of your Nissan's fuel system. For starters, it provides a seal for your fuel tank and stops dirt, water, and other harmful debris from getting into your gas supply. But, it has another purpose, too. The Fuel Tank Cap is also part of the EVAP, or evaporative emissions system, within your Nissan.
As your engine runs, the fuel in your vehicle heats up and emits dangerous byproducts. But, with a securely-fitted Fuel Tank Cap, the EVAP system can safely contain these exhaust gases to stop them from seeping out and contaminating the air around your vehicle.
If your Fuel Tank Cap doesn't make clicking sounds when it screws into its opening, or if it frequently loosens after you've already tightened it, you probably have a damaged or worn out gas cap. Because the cap is part of the EVAP system in your Nissan, your dashboard engine light may turn on if the fuel tank cap is faulty. Additional signals of a worn out Fuel Tank Cap include strong gasoline odors while you drive and diminished fuel mileage without having changed any of your travel habits.
Consider the consequences of a Fuel Tank Cap that's no longer functioning correctly. A Fuel Tank Cap with a busted seal may push harmful emissions into the environment, and it could also lead to a domino effect of other issues inside your Nissan and its engine. A worn out Fuel Tank Cap can diminish engine performance, lead to poor gas mileage, and create messy fuel leaks. It's wise to replace your Fuel Tank Cap as soon as you realize that it is not operating as it should.
Replacing a damaged Fuel Tank Cap couldn't be easier, and you can do it at home. You just need to shop directly with Nissan Genuine Parts to ensure a seamless fit for your vehicle.
