Strong fuel smell around generator during operation, but no visible leak and no code

Safety first: Ensure good ventilation and keep flames and sparks away. Turn OFF the generator before inspection.

• Check fuel cap: Ensure the Hyundai fuel tank cap is properly tightened and the seal is intact.
• Inspect fittings: Run a finger around fuel fittings and hoses to detect dampness. Tighten or reseal as needed.
• Exhaust inspection: Check for exhaust leaks at the manifold and joints that could direct fumes toward the intake or enclosure vents. Tighten or replace gaskets.
• Combustion check: If the engine runs visibly smoky or rough, have a technician check injection timing, carburetion (on petrol models), and air filter condition.
