- 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 Fuel Tank Cap is one component that isn't commonly talked about. You twist off the Fuel Tank Cap, fill your vehicle's fuel tank, and then secure it back on each time you fuel up, but that's probably the only time you think to acknowledge your fuel cap.
Your Fuel Tank Cap serves a vital role in the overall function of your Nissan. You already know that it provides a seal for your fuel tank and stops dirt, water, and other harmful debris from contaminating your gasoline. 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 temperature rises, and it releases dangerous byproducts. Fortunately, with the Fuel Tank Cap in place, your Nissan's EVAP system helps capture those fumes to stop them from leaking out into the atmosphere.
If your Nissan Fuel Tank Cap no longer clicks into its opening, or if it becomes loose after being tightened, you probably have an old or damaged cap. Since this component is also part of the EVAP system in your Nissan, your check engine light may turn on if the fuel tank cap is faulty. Other signs of an old Fuel Tank Cap can include strong gasoline odors while you drive and diminished fuel mileage (with no change in your driving habits).
There are several downsides to a Fuel Tank Cap that has cracked or worn down. A Fuel Tank Cap that doesn't seal properly can release harmful emissions into the atmosphere, but it can also create other significant problems in your Nissan. A failing Fuel Tank Cap can reduce your Nissan's engine performance, tank your gas mileage (no pun intended!), and create messy fuel leaks. It's wise to replace your Fuel Tank Cap ASAP once you realize that it isn't sealing or tightening properly.
Replacing an old Fuel Tank Cap couldn't be easier, and you don't need special tools to do it. All you need to do is shop with Nissan directly to enjoy a seamless fit for your vehicle.
