Having the right amount of gas in a car is vital in cranking and running the vehicle. Each of the components in the fuels system play a vital role in ensuring that the car runs as it should. The filler neck of the gas tank runs to the side of the vehicle and is where you will put in your gas. On the top of this filler neck is the fuel filler cap, which helps to keep water out of the gas tank. This part of the car is used on a constant basis, which is what leads to it becoming damaged over time.

In most cases, the fuel filler cap on a vehicle will have a seal under where the threads are attached. This seal helps to keep the moisture out of the gas tank. As time goes by, the seal will begin to deteriorate due to wear and tear. Usually, the seal will begin to dry out and will break apart. Not having this seal on the gas cap will lead to increased amount of moisture getting into the gas tank and wreaking havoc on the engine. Gas caps are designed to last for about 100,000 miles. In some cases, the gas cap will deteriorate at a rapid rate due to abnormally harsh conditions.

Taking the time to inspect the fuel filler cap on occasion will allow you to figure out if there are any issues that need to be addressed. If you notice that the seal is broken or if the threads on the cap are stripped, then a fuel filler cap replacement will be needed.

The following are some of the things to look for when it is time to replace the fuel filler cap.

  • The Check Engine Light comes on and stays on
  • The car will not pass an emissions test
  • The seal on the cap is broken or missing
  • The cap is completely missing

Noticing the signs that the fuel filler cap is damaged and acting quickly can help to reduce the amount of damage that is done.
