Strong raw fuel smell around generator during operation

Safety first: Shut down the generator, close fuel supply, disconnect battery negative, and ventilate the area thoroughly.

• Inspect fuel lines and fittings: Run your hand (with gloves) along hoses and fittings to feel for wet spots. Tighten loose clamps and fittings.
• Check tank and cap: Look for cracks in the fuel tank and ensure the cap seal is intact. Replace a damaged cap or tank.
• Observe exhaust: If black smoke is present, the engine may be running rich. Clean or replace the air filter and check choke operation.
• EFI systems: For fuel‑injected models, a leaking injector or rail seal may be the source. This should be diagnosed and repaired by a qualified technician.
