Depending on the cause, you can expect to pay anywhere between $150 to $1,500 to fix your vehicle’s leak. Gas leakages are incredibly dangerous to you, your car, and those around you, so it’s important you repair this issue as soon as possible—and avoid driving, if possible, until the repairs have been completed.
There are two main causes of gas leaks in cars: corrosion of the gas tank or a puncture of the gas tank.
A corroded gas tank might be easier to fix. Seams around the edges of the gas tank could have worn down over time, and this is much easier (and cheaper) to repair.
If you live in an area with a lot of snow and ice, your car’s undercarriage (where the gas tank is located) is especially prone to corrosion over time. However, if your gas tank was punctured, you might have to replace the entire tank.
Depending on the make and model of your car, the part alone can run upwards of $1,000, excluding the cost of labor.
