If your snow blower is leaking fuel, it’s important to address the issue promptly to ensure safe and efficient operation. A fuel leak can result from various causes, such as a cracked fuel line, a faulty carburetor, or a loose fuel cap. Here’s a step-by-step guide to help you diagnose and fix the problem.
Why is My Snow Blower Leaking Fuel?
A snow blower may leak fuel due to several reasons, and identifying the exact cause is crucial for effective repair. Here are the most common causes:
- Cracked Fuel Line: Over time, fuel lines can become brittle and crack, leading to leaks.
- Faulty Carburetor: A malfunctioning carburetor can cause fuel to overflow and leak.
- Loose or Damaged Fuel Cap: If the fuel cap is not properly sealed, fuel can leak out.
- Worn-Out Gaskets: Gaskets around the carburetor and fuel tank can degrade and cause leaks.

To fix a fuel leak, follow these steps:
- Identify the Source of the Leak: Start by inspecting the fuel lines, carburetor, and fuel cap for visible signs of damage or wear.
- Replace Damaged Parts: If you find a cracked fuel line or a faulty carburetor, replace these parts with new ones. Always use parts that are compatible with your snow blower model.
- Tighten Loose Connections: Ensure that the fuel cap and all connections are tight and secure to prevent leaks.
