How to Fix / Troubleshooting
Safety first: Isolate generator from load and prevent automatic start before servicing fuel system.
- Step 1 – Run no‑load test: Start the generator with all loads disconnected. If it runs smoothly, the issue is likely fuel delivery under load.
- Step 2 – Replace fuel filter: Install a new Kipor‑specified fuel filter and bleed air from the system.
- Step 3 – Check tank vent: Open the fuel tank cap slightly while running. If performance improves, clean or replace the tank vent.
- Step 4 – Test lift pump: Measure fuel flow from the lift pump into a container while cranking. Replace the pump if flow is weak or intermittent.
