Causes of Strong Smell of Petrol in Car – Inspections & Repairs

If your car smells like petrol while you are parked or driving, it can mean several different things. The smell could be caused by a minor problem or a serious safety risk. Either way, you should get it diagnosed as soon as possible to be safe.

Below are some of the most common causes of petrol fumes in your vehicle:

Leaking fuel line

The fuel line (or fuel hose) is responsible for delivering petrol from the tank to the engine. A leaking fuel line can be identified by the puddles of petrol that appear under your vehicle. When your fuel line is leaking, you may experience performance issues and increased fuel consumption.

It is important that you repair a leaking fuel line as soon as possible. This is because the high flammability of petrol can be a major fire hazard.

Leaking fuel injector

The fuel injectors are responsible for adding fuel to the engine. The fuel mixes with air to create a combustion process that allows the car to run.

If the fuel injector is leaking, you may notice a strong smell of fuel inside and around the car. Ths will often be accompanied by:

  • Increased fuel consumption,
  • Hard starting
  • Rough idling

A leaking fuel injector is also a fire safety hazard, particularly because of its location near the engines exhaust and ignition system. We suggest that you get your leaking fuel injector(s) repaired immediately!

Air / fuel mixture too rich

Your car may be burning more fuel than it needs to. This is often referred to as a rich air / fuel ratio. When your car burns too much fuel, there will be an increase in petrol fumes coming from your exhaust.

A rich air/fuel ratio will also result in:

  • Increased fuel consumption
  • Weak engine power
  • Rough idling
  • Increased emissions
