The fuel that resides in your gas tank is used to power your vehicle and to supply the material necessary for the combustion process. Ensuring that the gasoline in the tank remains at the proper consistency is important to the operation of the vehicle. The job of the gas cap is to make sure no debris or water gets into the fuel supply through the filler neck. The gas cap screws onto the top of the filler neck and has a seal that helps keep trash out. The gas cap is used all the time, which means you will have to replace the cap eventually.
The gas cap can last up to 50,000 miles, and in some cases longer if properly cared for. Not having this type of protection regarding the gas supply in a car can lead to a variety of different problems. If the gas cap leaves dirt and debris in the gas supply, then the fuel filter will usually clog. A faulty fuel filter will cause a restriction in gas flow, which means that it will be very difficult for the car to function normally.
The best way to detect damage with a gas cap is to take the time to inspect it regularly. You can usually tell if your gas cap is damaged, and repairing it quickly can reduce the damage it can cause. There are several different types of gas caps and selecting the proper replacement will take time and effort on your part.
When you need to replace a gas cap, here are some of the things you may notice:
- The check engine light is on
- The gas cap seal is visibly damaged
- The threads on the gas cap are worn or torn.
- The gas cap is missing
Putting a new gas cap on a car will help reduce the amount of trash that can enter your fuel supply. Getting advice from a professional on what type of gas cap can reduce the chance of error.
