Posted in: Diesel Generators Performance

To keep your generator working well and for a long time, it’s crucial to maintain it properly, including managing the fuel. Old or stale gasoline can cause problems such as starting issues. To maintain your generator’s health, learn how to safely and effectively drain gas when needed.

When to Drain Gas from Your Generator

Before we dive into the process, it’s essential to know when it’s the right time to drain gas from your generator. You should consider draining the gas:

  1. After an Extended Period of Non-Use: If your generator has been sitting idle for a while, it’s a good idea to drain the gas to prevent fuel-related issues.
  2. Before Long-Term Storage: If you’re planning to store your generator for an extended period, especially over the summer months, draining the gas is crucial to prevent fuel deterioration.
  3. Regularly: As part of your routine generator maintenance, it’s a good practice to ensure you always have fresh, stabilized gas in the tank.

Now, let’s get into the step-by-step process of draining gas from your generator.

How to Drain Gas from Your Generator

  1. Choose a Well-Ventilated Area: Start by moving your generator unit to a well-ventilated location to ensure safety during the process.
  2. Open the Gas Tank Cap: Loosen the gas tank cap to allow airflow throughout the system.
  3. Access Fuel Lines: Ensure easy access to the fuel lines. If there’s a plastic cover obstructing your way, remove it carefully.
  4. Turn Off the Fuel Valve: Switch the fuel valve to the “Off” position so that it’s closed when you remove one side of the fuel line.
  5. Disconnect the Fuel Line: Locate the clip securing the fuel line that doesn’t connect to the gas tank. Carefully remove the clip and then detach the tube from the fuel valve.
  6. Prepare a Container: Position a bowl or container beside the generator. Place the end of the fuel valve tube into the container. Slightly tilt the generator so that all the fuel flows towards one side and runs out of the disconnected fuel line.
  7. Turn On the Fuel Valve: Once most of the fuel has drained, switch the fuel valve back to the “On” position to drain any remaining fuel from the generator.
  8. Reconnect the Fuel Line: Carefully reattach the fuel line, ensuring it’s securely in place. Close the lid on the fuel tank and, if applicable, reattach any covers or plastic casings.
  9. Locate the Carburetor: Refer to your generator’s manual to locate the carburetor. Remove the bolt from the carburetor and let any remaining gas flow out into the container.
  10.  Secure the Bolt: Using pliers, reinstall the bolt onto the carburetor, ensuring it’s tightly secured.

Regularly draining gas from your generator is a simple yet crucial maintenance task that helps ensure its reliability and longevity. By following these steps, you can keep your generator in top working condition and be ready for any power needs that may arise. Proper care today ensures your generator will be there for you when you need it most.
