A car in good condition does not smell like gas. So, if you find that your car smells of gasoline while parking, it looks like there are internal problems with your vehicle. And these problems must be rectified immediately. In this article, we'll show you some possible reasons why a car smells like gas and how to fix it.

1.
Tank cap

If you find that your car smells of gasoline after driving, pay attention to the fuel tank cap. After opening the tank, you must carefully inspect the fuel cap and make sure that you never lose it or loosen it. In addition, you must
ensure that the fuel cap is still in good condition. A defective or loose gas cap may release gas and turn on the new vehicle light. Thanks to the amazing technology behind the check-engine display, the car can now detect leaks through a self-test.

2.
Gas load

The reason for thinking about when a car smells of gas but has no leaks is exposure to gas. In some cases, gasoline exhaust from gas station pumps can get into your car when you open the car doors or windows and cause gas odor. To solve this problem, just roll down the windows and drive for a few minutes. If the smell of gas does not come back, you do not have to worry about it anymore, you should look for other reasons below.

3.
Cracked canister

Canister is a plastic component for catching charcoal. The vessel also collects excess steam exiting the fuel tank to minimize emissions emanating from the system. If the canister spills or ruptures through the damaged vent or gasket, you will smell a strong gas vapor in your car. This will turn on the indicator light.

4.
Gas Discharge

Gas leaks are another reason why the car smells of gas. You can check whether there are gas leaks in your car or not by looking for black puddles under the car. If the car has black puddles, here are some things you should check:

a. Fuel tank

Punctured or old fuel tanks often cause gas leaks. The best way to fix this problem is to completely remove the tank. In this way, the mechanic can thoroughly check for fixation or replacement.


b. Injector

Injection leaks are caused by their O-ring seal or rubber. All injectors have a rubber seal at the bottom and an O-ring at the top. These components tend to be broken by dryness. To correct this problem, you only need to replace the damaged O-ring or gasket. You do not have to restore the entire injector.

To check the state of the injector, you must open the bonnet and inspect the injector in the fuel rail. Turn on the engine. If you find out that the fuel is stored around the injector, your car smells of gas.

c. Fuel injection line

A leak in the fuel injection pipe can cause a strong gas odor when you park your car. The function of fuel injection promotes higher pressure along the fuel lines. For new cars, the pressure is between 60 psi and 125 psi. When problems occur in the fuel injection, such as a slight adjustment, the fuel is distributed from different parts of the line. This leads to fog and steam, which generate gas odor. In fact, this is very dangerous if the leak is near the exhaust or engine. In addition, gas mist is very dangerous to health. When a person inhales gas smoke, they experience dizziness or headache, which eventually leads to brain damage if these leaks are not corrected immediately.

d. Fuel line

Fuel lines attach the fuel tank and the engine. They are under cars. Dirt and various elements along the road can easily crush fuel lines. Rubber-made parts tend to leak if used for several years or broken by a clumsy mechanic.

5.
Bad fuel pressure

Bad fuel pressure is one of the possible reasons why a car smells of gas. A faulty pressure regulator can cause your car to burn fuel until the mixture gets too rich or too thin. If you burn more fuel, gas fumes may be created in the exhaust. Gases also penetrate into the vehicle when the exhaust gas enters the ventilation system through a leak. In this case, the smell is not the only symptom of a fuel pressure regulator. Another warning sign is the weaker performance and fuel efficiency.

6.
Ancient cars

Vehicles made in the early 1980's or earlier are likely to trigger a faint gas odor after stopping. This happens due to the re-drilling of the fuel in the float shell of the carburetor. It is perfectly normal if you notice the smell only after the car is parked and disperse after a while. Newer models do not have this problem because they have a built-in evaporative emission system.

POINTS TO NOTE

Gasoline are volatile in the atmosphere, it is very essential to observe gasoline smell in the car, ability to do this reduces death rate and prevent unnecessary damage to the car
