Fuel Tank Cap.

• 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 INFINITI Fuel Tank Cap is one component that isn't commonly talked about. You remove 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 an important purpose in the efficiency of your INFINITI's fuel system. You already know that it creates a seal for the fuel tank and prevents moisture, debris, and dirt from seeping into your gas supply. But did you know? The Fuel Tank Cap is an integral part of your INFINITI's evaporative emissions system (or EVAP).

When you're driving, the fuel in your vehicle heats up and emits dangerous byproducts. But, with the Fuel Tank Cap in place, your INFINITI's EVAP system can catch and recirculate those emissions to prevent them from being released into the surrounding atmosphere.

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 likely have a worn out gas tank cap. Since this part is a component in your engine's overall EVAP system, your dashboard engine light may illuminate if the fuel tank cap is faulty. Additional signals of a damaged or worn Fuel Tank Cap may include strong gasoline odors while you drive and lower fuel mileage without having changed any of your travel habits.

Consider the drawbacks of a Fuel Tank Cap that's not working as it should. A Fuel Tank Cap that doesn't seal properly can release damaging byproducts into the air around your INFINITI, but it can also cause a domino effect of other issues within your INFINITI's engine. A failing Fuel Tank Cap can reduce your INFINITI's engine performance, tank your gas mileage (no pun intended!), and create messy fuel leaks. It's wise to replace your Fuel Tank Cap as soon as you realize that it is no longer functioning correctly.

Replacing an old Fuel Tank Cap is simple, and you don't need special tools to do it. You just need to shop genuine INFINITI parts online to enjoy the best possible fit.
