Gas tank replacement
The fuel tank is a part of the car and a component of the fuel system, designed for storing and transporting fuel. It is usually made of steel, aluminum, or plastic. The driver refuels the tank through the filler neck at the gas station. The location of the tank generally depends on the car model. Main symptoms that should not be ignored for safety reasons include the smell of fuel inside and around the car, the presence of leaks or fuel stains under the car, and particularly if you notice through the fuel level gauge that the amount of fuel is decreasing while the engine is off.
If you notice any of these symptoms, you should go to a car repair shop for further inspection and diagnosis of the vehicle's fuel system. Ignoring these issues can pose a threat to your safety and lead to fire or other dangerous consequences. A repair specialist will be able to assess the condition of the fuel tank and provide effective and, most importantly, safe repair of your car.
Common defects of the fuel tank include corrosion and rust, which can develop due to prolonged use of the vehicle, especially under harsh conditions; dents; punctures; and tears incurred from running into obstacles or other objects on the road. Depending on the extent of the defects and the recommendations of a professional mechanic, the fuel tank may be subject to repair or replacement.
It is very important to understand that repairing a fuel tank using welding or a grinder to cut metal involves safety measures, as the presence of fuel vapors can trigger an explosion of the gas mixture and lead to undesirable consequences for both your health and financial losses. It is very difficult to completely eliminate fuel vapors when rinsing the fuel tank, so for safety reasons the tank is steamed (blown out with steam) for several hours or pressurized with carbon dioxide or argon. Also, for minor repairs like patching, it is sometimes possible to simply fill the fuel tank with water. If small defects are detected on the road, you can temporarily perform the repair yourself. If there are punctures or small holes, you can apply a fabric patch with adhesive, or paint, you can use cold welding, or use a self-tapping screw with a rubber plug by simply screwing it into the hole. All these actions are strictly temporary and we recommend using them only to continue driving to an auto repair shop.
When replacing the fuel tank, keep in mind that fuel tanks for cars can vary in manufacturing materials:
- Metal, usually steel. The advantage is strength and resistance to mechanical damage, and they are repairable. The disadvantages are that they are susceptible to corrosion and rust, especially in harsh climatic conditions.
- Plastic, usually high-density polyethylene. Many modern cars have plastic tanks. Advantages include light weight, corrosion resistance, and being more affordable, but they are less repairable.
- Aluminum tanks - the advantages are lightweight and corrosion-resistant. The disadvantages are that they are susceptible to mechanical impact and are expensive.
The choice of fuel tank depends on your budget, climatic conditions of operation, and safety requirements. Modern materials and fuel tank designs provide a longer service life and reliable protection against fuel leaks. Maintaining the tank in good condition and its proper servicing impact the prevention of problems related to the repair of the fuel tank.

Check Engine Light
The yellow check engine light commonly warns that the engine releases more emissions than expected, often due to a catalytic converter failure. This causes engine misfires, poor fuel mileage, low power, and more. But there are alternative common causes for this issue.
The most common causes for the Check Engine light are:
- Engine misfire: When an engine misfires, it fails to ignite the air-fuel mixture properly, leading to a loss of power and rough running. The onboard diagnostics system detects this issue and triggers the check engine light.
- Evaporative emission leak: An evaporative emission (EVAP) leak can cause the check engine light to illuminate because it disrupts the vehicle's emissions control system. A leak in the EVAP system, allows fuel vapor to escape, leading to increased emissions.
- Loose gas cap: If the gas cap is not properly tightened or is missing, it can allow fuel vapors to leak out, triggering the check engine light.
- Faulty airflow sensor: The airflow sensor measures the amount of air entering the engine to help the system adjust the fuel injection for a perfect air-fuel mixture. If the sensor fails, it'll cause a bad mixture and trigger the check engine light.
- Faulty catalyst: The catalytic converter converts harmful gases into less harmful emissions. If the catalyst is faulty, it increases emissions and triggers the check engine light.
- Lean codes: Lean codes can cause the check engine light to illuminate because they indicate a problem with the air-fuel mixture in the engine. A lean condition occurs when there is too much air and not enough fuel in the air-fuel mixture, leading to incomplete combustion.
- Faulty variable valve timing (VVT): The VVT system controls the timing of the opening and closing of the engine's valves. If the VVT system is faulty, it may not operate correctly, leading to issues such as rough idle, reduced power, and increased emissions, triggering the check engine light.
Stay alert if the check engine lights up on your car's dashboard. Your vehicle might be under progressive damage and can end up requiring hefty repairs in the future; it'll also show considerable fuel loss. So please, keep track of your car's odd behaviors and browse through our articles to find out the information you'll need to share with your go-to auto shop.
Car Leaking Gas
The gas leak is commonly caused by a crack or looseness in the fuel tank. However, it can also be caused by a misplaced gas cap, faulty fuel injectors, damaged fuel lines, valve leaks, or even a broken sensor allowing fuel leaks.
Gas powers our vehicles because of its flammability. So, when it leaks, it reasonably causes concerns. But, in addition to the fire hazard, gas vapors are toxic and harmful to the environment.
A vehicle's "check engine light" may indicate a fuel leak, and the "gas cap light" ensures your fuel system is sealed. Remember, this pressurized, sealed part is designed to safely contain fuel and harmful vapors.
Gas leaks are easy to detect since they strongly smell and leave puddles under your vehicle. But, sadly, gas leaks don't only put the driver in danger but everyone around the car as well.
Evap System Leak
When it comes to our vehicles, we all want them to run smoothly. But sometimes, pesky problems like Evap system leaks can throw us off track. This type of issue typically leaves trails, such as a fuel smell.
An Evap leak is when your vehicle's Evaporative Emission Control system, which is responsible for keeping fuel vapors in check, develops a minor breach. So instead of those vapors staying where they should, they sneak into the air.
Paying attention to the signs and taking action can save you some headaches and money in the long run. So, if you catch a whiff of gasoline or that "Check Engine" light starts acting up, don't brush it off. Your Evap system might just be trying to get your attention.
