my Toyota RAV4 Fifth Generation (2019-present) has a strong smell of gasoline

Solution

1. Preparation

• Tools Required: Safety gloves, safety goggles, jack and jack stands, fuel pressure gauge, OBD-II scanner, basic socket set.
• Safety Warnings: Disconnect the battery before working on electrical systems and allow the engine to cool before inspecting components.

2. Inspect and Replace Fuel Cap

• Remove the fuel cap and inspect for cracks or damage.
• If damaged, replace with a new fuel cap, ensuring it fits securely.

3. Repair Fuel Lines

• Tools Required: Socket set, wrenches, replacement fuel line(s) as needed.
• Locate the section of the fuel line that shows visible wear or leaks.
• Using a wrench, carefully loosen the clamps securing the fuel line.
• Remove the damaged section and replace it with a new fuel line, securing it with clamps to manufacturer specifications.

4. Replace or Repair Fuel Injectors

• Tools Required: Torque wrench, socket set, replacement fuel injector(s) if necessary.
• Disconnect the fuel rail and remove the fuel injectors.
• Inspect for signs of wear or leakage. If damaged, replace with new injectors.
• Reassemble the fuel rail and ensure all connections are tight.

5. Test Fuel Pressure

• Attach the fuel pressure gauge to the fuel rail.
• Turn the ignition to the ON position (but do not start the engine) and check the pressure reading.
• Compare the reading to manufacturer specifications; replace the fuel pump if pressure is out of specification.
