Yes, a loose o r cracked fuel cap can definitely cause petrol vapors to escape, especially when the tank is full o r during hot weather. These vapors can seep into the cabin, especially if the rear seat o r trunk is not well-sealed.

Common Symptoms:

Strong petrol smell near the fuel door o r inside the cabin

Smell increases after refueling o r in direct sunlight

Solution:

Inspect the fuel cap for cracks o r worn-out threads

Make sure the cap clicks tightly when closed

Replace the cap if the rubber gasket is missing o r cracked

You can find replacement caps easily in Pakistani auto markets like Montgomery Road Lahore o r Plaza Karachi.
