It’s a good thing you noticed the leaking gas; gas leakages are incredibly dangerous to you, your car, and those around you. It’s important you fix this ASAP and avoid driving, if possible until the repair has been made. Depending on the cause of the gas leak, it can cost you as low as $150 up to $1,500 to fix your car’s gas leak.
There are two main causes of gas leaks in cars: corrosion of the gas tank or a puncture of the gas tank.
However, if your gas tank was punctured, you might have to replace the entire gas tank. Depending on the make and model of your car, the part alone can run upwards of $1,000**, excluding the cost of labor.
