To know more in detail, this article presents to you eight common reasons why your car might smell petrol. Also, you will gain valuable insights about how to prevent your car from such smells, malfunctions and fuel tank vent issues.
1. Fuel Leak in the System
Fuel leaking in the pipeline or in the engine is one of the common causes of petrol leaks in your car. These leaks can be present in the fuel tank, hoses, connectors or injectors. You may also notice drops of fuel on the ground beneath the car. In another aspect, you may notice that the car is consuming more fuel than usual rate. Fuel leak symptoms increase when your car is parked, as the spills of fuel drops on the ground.
If you suspect any of these leaks, visit an auto car mechanic for a full inspection of your fuel injection system. To fix these issues, they will look at the car’s fuel tank, seals and many more places to find and fix the leak.
2. Faulty Fuel Injector Seal
To ensure the car is running smoothly, fuel injectors spray petrol into the engine. If the rubber seals or O rings around fuel injectors wear out, petrol can leak. This situation may result in a strong smell inside the car.. You may also notice the engine malfunctioning during such instances.
To fix such issues, a trusted car mechanic Adelaide inspects fuel injectors, fixes them, or sometimes they have to replace the worn seals.
3. Cracked or Damaged Fuel Lines
Fuel lines are basically pipes that carry fuel from the tank to the car’s engine. With frequent or long-term usage, this pipe may wear out. As a result, a damaged link leaks petrol and vaporises it, which creates a strong smell around your car.
To fix such issues, automotive repair shops run a pressure test on the fuel system to check for hidden cracks or leaks in the lines.
4. Faulty Fuel Pressure Regulator
The car’s fuel pressure regulators control how much petrol reaches the engine. If this part malfunctions, the valve can force more fuel than the required rate or vice versa. As a result, it can cause multiple issues in the car’s engine, such as rough idling, stalling, poor acceleration and reduced fuel efficiency. If you smell fuel beside your car’s engine, then it might be a sign that the fuel is being burned more than the required rate.
To test the fuel pressure of the engine, you can take your vehicle to a car repair service. If required, the regulator can be replaced to avoid fuel burn and calibrate petrol usage.
5. Blocked Fuel Tank Vent
Cars usually have sealed fuel systems, but they still may need a way to release pressure, this is where the fuel tank vent is useful. If this part becomes blocked or faulty, then you may face difficulty in filling the fuel tank, or the engine may suddenly stop working.
To identify this issue, you can avail of the logbook service Adelaide, where all important part of the car is checked.
6. Leaking or Loose Fuel Cap
During the filling of fuel, if you don’t properly tighten this cap, the seal may wear out, petrol vapours may escape and even the risk of water contamination increases during car wash or rain. A loose cap is the common reason for the petrol smell after filling up the tank.
To confirm if it closely fits or not, ask your car mechanic Adelaide during routine car checks.
7. Issues with the Exhaust System
Sometimes the smell of petrol comes from the air exhaust vents. This can show that your car’s engine is running on excessive fuel and not enough. A strong petrol smell near exhaust also suggests that the unburnt fuel is making its way out.
To check the root cause of this issue, your vehicle may need a car service Adelaide for testing the car’s engine tuning and emissions.
8. Problems Inside the Engine Bay
Leakage of fuels under the engine bay often happens from injector lines, fuel rails or issues with the Evaporative Emission Control (EVAP) system. This smell can get into the cabin where you drive the car through the air vents. You may also notice this smell when you lift the bonnet of the car. You should immediately check and fix strong petrol fumes from engine bay because this occurrence can lead to fire hazards and health risks for the car’s passengers.
During a log book car service, mechanics often inspect the engine bay for fuel smells, leaks or worn parts to avoid danger.
