How do I change the fuel lines on my Petrol Chainsaw

This article explains how to replace and correctly route the fuel lines on your petrol chainsaw.

⚠️ Safety Notice

Ensure the chainsaw is switched off and completely cooled before carrying out any maintenance.

Work in a well-ventilated area away from open flames or ignition sources, as fuel is highly flammable.

When Fuel Lines Need Replacing

Fuel lines may need replacing if:

• The chainsaw is difficult to start
• Fuel is leaking from the machine
• The engine is running inconsistently
• The fuel lines appear cracked, brittle, or damaged

Important Information

Fuel line routing can vary depending on the model of chainsaw. Always refer to the correct diagram for your specific machine, including part numbers where provided.

Fuel Line Replacement (General Guide)

1. Remove any remaining fuel from the tank safely.
2. Open the fuel tank access area where applicable.
3. Carefully remove the old fuel lines, noting their original routing positions.
4. Compare the new fuel lines with the originals to ensure correct length and fit.
5. Install the new fuel lines following the correct routing diagram for your model.
6. Ensure each line is securely seated and not kinked or pinched.
7. Refit any components removed during the process.
8. Refill with the correct fuel mixture before testing.

Important Tip

Correct routing is essential for proper fuel delivery. If the lines are connected incorrectly, the engine may not start or may cut out during use.
