If your car is leaking gas from the fuel pump, it could be due to a damaged fuel pump or a crack in the fuel line. This can be a fire hazard and can damage the engine. Fuel pumps should be inspected regularly for signs of wear and tear.

What You'll Learn
Cracked fuel line
The fuel line on a modern vehicle is a rigid, high-pressure plastic with quick-disconnect fittings that are formed on both ends. It's designed to carry the fuel from the gas tank to the injector rail. If the plastic line develops a crack or the rubber seals in the quick disconnects degrade, the line will start leaking as the fuel pump runs. Since the pump is idle, you'll notice gasoline puddling underneath the vehicle. You might also notice that the engine is difficult to start or the motor oil seems thin.
The fuel pressure sensor on top of the fuel pump module detects pressure in the fuel tank to verify that no fuel vapor leaks into the atmosphere. If you lose pressure because of a seal leak, the "check engine light" will come on. The engine might also be hard to start at other times, and you might smell gas when opening the hood.
The fuel injectors are responsible for delivering gasoline to the engine. Over time, they can become clogged with dirt and debris, which can cause them to leak. If you notice that your fuel injectors are leaking, it’s important to have them cleaned or replaced as soon as possible.
The fuel pump is responsible for drawing gasoline from the tank and delivering it to the engine. If the pump becomes damaged, it can leak gasoline onto the ground or into the engine compartment. This can be a fire hazard and can damage the engine. Fuel pumps should be inspected regularly for signs of wear and tear.

The purge control valve is designed to stay closed, only occasionally opening to evacuate gas fumes accumulated in the charcoal canister. This helps to dry out the canister. However, if this valve fails and sticks open, adding fuel to the tank forces gas fumes into the intake, flooding the engine.
The fuel injectors are responsible for delivering gasoline to the engine. Over time, they can become clogged with dirt and debris, which can cause them to leak. If you notice that your fuel injectors are leaking, it’s important to have them cleaned or replaced as soon as possible.
