What Should I Do If My Vehicle Is Leaking Fuel?

A leaking fuel line can be discovered by looking for puddles or stains underneath the vehicle when parked, usually with a strong fuel odor. 

A fuel injection line may also leak, causing a smell of fuel fumes during and immediately after driving. A fuel tank vent hose may also leak, causing unburnt fuel to exit the fuel system as vapor.

The fuel gauge may drop a small or large amount, depending on the size of the leak. If you have noticed this, please recommend an inspection to determine if the tank is leaking. But in every case of a suspected fuel leak, please ensure the vehicle is towed to the dealership in order to minimise the risk of fire and/or injury to the driver or other road users.
