Noticeable diesel smell around the generator even when no visible leaks are present.

Safety: Ensure good ventilation and avoid smoking or open flames near the generator.

• Inspect leak‑off lines: Check small return hoses on top of injectors for dampness or cracks. Tighten clamps and replace aged hoses.
• Check tank breather: Ensure the fuel tank breather is not blocked and is routed away from air intakes.
• Wipe and monitor: Clean suspected areas and run the engine briefly, then re‑inspect for fresh dampness.
• Seal replacement: If pump or union seals are weeping, schedule replacement during planned maintenance.
