Possible Causes
How to Fix / Troubleshooting
Safety: Shut down the generator, disable automatic start, and eliminate all ignition sources. Do not smoke or use open flames nearby.
- Visual inspection: Follow all visible fuel lines from the tank to the engine. Look for wet spots, drips, or stains.
- Check filter and fittings: Inspect the fuel filter housing and connections. Tighten loose fittings and ensure the filter is properly seated with a good gasket.
- Inspect hoses: Flex hoses gently and look for cracks or soft spots. Replace any suspect hoses with CAT-approved fuel hose.
- Test after repair: Wipe up spilled fuel, ventilate the area, then run the generator and recheck for leaks.
If you cannot locate the source of the fuel smell or it appears to come from inside the engine, contact a CAT technician. Do not operate the generator with an unresolved fuel leak.
