How can you know the Fuel Tank Filler Cap, gas cap needs replaced?
1.Cap does not tighten properly
Most Fuel Tank Filler Cap/gas caps are designed to click once they are tightened sufficiently. If the cap does not click, or clicks and then pops loose again then that may be a sign that it may need to be replaced.
2.Fuel smell from the vehicle
If the Fuel Tank Filler Cap/gas cap seal becomes damaged or worn it may cause fuel vapors from the gas tank to leak from the filler neck. This may result in a gasoline odor from the vehicle as a result of the escaping vapors.
3.Check Engine Light comes on
If you suspect that your gas cap may be having an issue, please take a minute to check the gas
