How to Fix / Troubleshooting
Safety first: Stop the generator, isolate electrical power, and eliminate all ignition sources. Use absorbent materials to contain spills.
- Trace the leak: Wipe down fuel system components and observe where fresh fuel appears. Pay attention to hoses, filters, and tank seams.
- Replace damaged hoses: Use SDMO-approved fuel hoses and clamps. Cut back to clean pipe ends before refitting.
- Tighten fittings: Carefully tighten filter heads, banjo bolts, and compression fittings. Do not overtighten plastic components.
- Inspect tank: Check the SDMO base tank or external tank for corrosion or cracks. Repair or replace as necessary.
- Test under operation: After repairs, run the generator and recheck for leaks before returning to service.
