Chevrolet Cavalier Fuel Tank Troubleshooting Tips

Unless you're running out of gas, and the 'empty' signal on your dashboard is lit up, then that is the only time that you give concern to your Chevrolet Cavalier fuel tank. Your fuel tank is usually a neglected part of your vehicle. For one, you don't expect it to wear out easily because you don't really check its condition; only the amount of fuel it contains. But when it breaks down, you'll be surprised that you didn't see it coming. Here are some troubleshooting tips that can help you prepare for the problems you might encounter with your fuel tank:

Rust sediments

Usually steel-made, your vehicle's fuel tank could be at risk of corrosion. Did you know that when you keep your tank half-full, it becomes more prone to corrosion? Since there is enough space for vapor and moisture to build up, they eventually cause the steel to rust. When this happens, rust sediments can accumulate and sink on the lower part of the tank. You can empty the tank and remove all these sediments, or you can either replace the tank if it is totally corroded. Fuel won't be able to flow smoothly in a corroded tank and it may even become contaminated.

Fuel contamination

This is a common fuel tank problem that can be addressed beforehand. Usually, fuel becomes contaminated due to the impurities that might be present in a dirty fuel or other substances. Regular cleaning of the fuel tank is advised to ensure that it won't be susceptible to rust build-up. If you have a contaminated fuel, it will reflect on your vehicle's performance. There would be rough idles, loss of power, and stalling, among others. You need to empty the fuel tank and clear it from debris or impurities before you reinstall it.

Fuel return lines fracture

If there is any problem with the fuel return lines, then it could be a cause of a greater problem. Faulty fuel lines could cause a fire if it creates a spark or excessive heat underneath the vehicle. You should inspect the fuel tank and its lines for any cracks or damages that might cause the fuel to leak. Replace the damaged fuel return pipe assembly, if necessary.

  • Top Three Ways to Maintain your Chevrolet Cavalier Fuel Tank 27 February 2013

    Your Chevrolet Cavalier fuel tank is typically steel-made to prevent corrosion from moisture. Replacement parts also offer a multi-layered construction design to keep it rust-free. However, no matter how durable your fuel tank is, it still needs proper maintenance for it to have a long service life. Dirty gasoline or cracks due to age could be some of the culprits that could cause it to wear out. Below are some ways to keep your Cavalier's fuel tank more durable:


    Keep your tank full.

    Did you know that by keeping your tank full, you are already protecting it from corrosion? Whenever a tank is below the gas level, it is filled with air. And since air contains a lot of water vapor, it eventually becomes the cause of rusting inside your metal tank. Once the rust gets in your tank, it is more likely to sink to the bottom and become a sediment that isn't really good for your car. So if you usually drive with a half-empty tank, then it's like you're letting rust to live inside it.


    Inspect your tank's condition.

    Nothing beats a thorough inspection of the fuel tank and its parts for leaks and cracks. Look for signs of corrosion, such as rust spots. In case you just bought a new OEM or aftermarket fuel tank, we advise that you apply rust-proofing spray to it before installing it. Ensure that the caps are tightened and that they are not leaking. Replace lost or leaking caps immediately. You may also look for damaged fuel lines that may cause the fuel to leak.


    Clear your tank from debris.

    Keeping your tank clean as much as possible is a secret to its prolonged lifespan. When your tank is empty, it would help if you will take time to remove all the dirt and debris that are inside it. Clear all insect nests, snow, or other dirt buildup that are trapped in the tank. This is to ensure that the tank will be able to vent properly, which will reflect in your vehicle's performance. Also, remove rust spots that may cause the tank to corrode and leak.
