Do you smell gasoline fumes as you are driving your car? Well, this is something that many car owners experience. The good thing is that you can diagnose and fix the smelling gas issue by yourself. I am going to explain why your car smells like gas when you accelerate and how to fix it.
Why does my car smell like gas when I accelerate? Your car smells like gas when you accelerate because your gas cap could be leaking gas, the fuel injectors could be leaking gas, or your car just is running poorly and you are smelling the gasoline coming out of the exhaust.
Why Does My Car Smell Like Gas When I Accelerate
The gas smell in your car is associated with some faulty part of the fuel system. It can be as easy as a loose gas cap, or something more serious as bad fuel injectors. Here is why your car smells like gas when you accelerate:
1. Gas cap is leaking fuel
Will my car smell like gas if the gas cap is broken? Your car could smell like gas when you accelerate if the gas cap is loose or completely missing. The gas caps are supposed to seal the fumes in. If the rubber is ripped or torn, or the valve inside is broken, fuel vapors will escape and you are going to smell gas when you drive your car.
Many people think that they have a major problem because their car smells like gas when they drive it. But, in reality, the issue could be as small as a broken or loose gas cap.
2. Charcoal evaporation canister leaking fuel
What happens if my evaporation canister starts to leak fuel? If the charcoal evaporation canister is faulty and is leaking fuel, your car could smell like gas when you accelerate. The charcoal evaporation canister is a part of the anti-pollution system and can be found under the hood or on top of the gas tank. It depends on the vehicle.
If the charcoal evaporation canister is located under the hood of your car, it would be very easy for you to locate the problem. If the canister in your car is located on top of the fuel tank, then you will have to take your vehicle to the mechanic.
3. Gasoline drips from the fuel system
If your fuel filter, hose connections, or any rubber part of the fuel system is broken or loose, gas will be dripping on the ground and your car will definitely smell like gas when you drive it.
To diagnose the gasoline dripping, you have to get under the car and check all of the fuel lines. You can also park your car on your driveway overnight and see if there are any gas drips on the ground. Look very closely because your car could be dripping as little as a couple of drops and it will still smell of gas while you drive it.
If you don’t find any leaking on the ground, check under the hood. Follow the fuel rail and look for any potential leaks. What’s great about gas is that it is a great solvent. So, if there is a leak and find a really clean area where everything shiny, you know that’s the part that’s leaking.
4. Use UV Dye to check for leaks
Sometimes, fuel leaks are harder to find. If you are unable to locate any leaks underneath the car or in the engine bay area, you can use a UV Dye. The UV Dye is a product that you pour into the gas tank and let your car run for 20 minutes. Then, with ultraviolet light, check the fuel system line for any potential leaks.
