Fuel Injector Leak: A malfunctioning fuel injector or a faulty seal can cause fuel to leak into the intake manifold, resulting in a strong gasoline smell. To check for a fuel injector leak, remove the air cleaner housing and inspect the injectors for any visible signs of leakage.

Faulty Fuel Pressure Regulator: A faulty fuel pressure regulator can cause excessive fuel pressure, leading to fuel leaks and a strong fuel smell. To test the fuel pressure regulator, connect a fuel pressure gauge to the fuel line and check if the pressure is within the specified range mentioned in your vehicle's service manual.

Clogged Fuel Filter: A clogged fuel filter can restrict fuel flow and cause the fuel system to build up pressure, potentially resulting in fuel leaks. To check the fuel filter, locate it in the engine bay (usually near the fuel tank) and inspect it for any visible signs of dirt or debris.

Loose or Damaged Fuel Line: A loose or damaged fuel line can cause fuel to leak out and create a strong gasoline smell. Inspect the fuel lines for any cracks, holes, or loose connections.

Faulty Fuel Tank Cap: A faulty or loose fuel tank cap can prevent the fuel tank from sealing properly, causing fuel vapors to escape and creating a strong gasoline smell. Make sure the fuel tank cap is properly tightened.
