- Fuel System: Look for leaks around the fuel lines, fuel filter, and fuel injector seals.
- Gas Cap: Ensure that the gas cap is properly tightened. A loose or damaged gas cap can cause fuel vapors to escape.
- Fuel Tank: Check the fuel tank for any leaks, especially around the seams and drain plugs.
- Evaporative Emissions System: Inspect the evaporative emissions system, including the purge valve, canister, and vacuum lines, for any leaks or damage.
- Exhaust System: Check the exhaust system for leaks, particularly near the exhaust manifold and catalytic converter.
If you can't find any apparent leaks after checking these areas, it's recommended to have your Volvo S80 inspected by a professional mechanic or automotive technician. They have the necessary tools and experience to pinpoint the source of the gas smell and ensure your safety.
