What To Know

  • Whether it’s for storage, transportation, or repairs, knowing how to drain gas from a Generac generator is essential for its longevity and safety.
  • Place a suitable container, such as a gas can or a bucket, beneath the fuel drain valve.
  • Remove the drain plug and allow the remaining gas in the carburetor to drain into the container.

In the realm of power generation, Generac generators stand as reliable companions, providing backup electricity during outages. However, when it comes to maintenance, one crucial task that every generator owner must master is removing gas from their Generac unit. Whether it’s for storage, transportation, or repairs, knowing how to drain gas from a Generac generator is essential for its longevity and safety.

Why Remove Gas from a Generac Generator?

There are several reasons why you might need to remove gas from your Generac generator:

  • Storage: Draining the gas is crucial before storing your generator for an extended period. Gasoline can deteriorate over time, forming harmful deposits that can clog fuel lines and damage the engine.
  • Transportation: When transporting a generator, it’s essential to empty the fuel tank to prevent spills and potential hazards.
  • Repairs: Removing gas may be necessary for repairs, such as carburetor cleaning or engine overhauls.

Safety Precautions

Before embarking on the gas removal process, prioritize safety:

  • Shut Off the Generator: Ensure the generator is turned off and cooled down before proceeding.
  • Disconnect the Spark Plug: Disconnect the spark plug wire to prevent any accidental ignition.
  • Ventilate the Area: Open doors and windows to provide ample ventilation and prevent the buildup of gasoline fumes.
  • Wear Gloves and Safety Glasses: Protect your hands and eyes from potential fuel spills.

Step-by-Step Guide to Removing Gas from Generac Generator

1. Locate the Fuel Drain Valve

Generac generators typically have a fuel drain valve located near the bottom of the fuel tank. It may be a small plastic or metal valve with a lever or handle.

2. Position a Container

Place a suitable container, such as a gas can or a bucket, beneath the fuel drain valve. Ensure the container is large enough to hold the remaining gas in the tank.

3. Open the Fuel Drain Valve

Slowly open the fuel drain valve by turning the lever or handle. Allow the gas to drain into the container.

4. Drain the Carburetor

Once the fuel tank is empty, it’s necessary to drain the carburetor. Locate the carburetor drain plug, which is usually a small screw or bolt. Remove the drain plug and allow the remaining gas in the carburetor to drain into the container.

5. Close the Fuel Drain Valve and Carburetor Drain Plug

Once the gas has drained, close the fuel drain valve and carburetor drain plug securely.

6. Run the Generator for a Few Seconds

Connect the spark plug wire and start the generator briefly. This will help remove any remaining gas from the fuel lines and carburetor.

7. Shut Off the Generator and Disconnect the Battery

Finally, shut off the generator and disconnect the battery. This will prevent any accidental ignition or battery discharge during storage or transportation.

Tips for Safe Gas Storage and Disposal

  • Store Gas in Approved Containers: Use only approved gas cans or containers that are specifically designed for fuel storage.
  • Store Gas in a Cool, Dry Place: Keep gas containers in a well-ventilated area away from direct sunlight and heat sources.
  • Dispose of Gas Properly: Never pour gas down the drain or on the ground. Contact your local waste management facility for proper disposal methods.

What You Need to Know

1. Can I use a siphon to remove gas from my Generac generator?

Using a siphon is not recommended as it can introduce air into the fuel system, causing problems when starting the generator.

2. How often should I remove gas from my Generac generator?

If you don’t plan to use your generator for an extended period (over 30 days), it’s advisable to remove the gas.

3. What happens if I don’t remove gas from my Generac generator before storing it?

Leaving gas in the generator can lead to fuel deterioration, clogged fuel lines, and engine damage.

4. Can I use a fuel stabilizer instead of removing gas?

While fuel stabilizers can extend the life of gasoline, it’s still recommended to remove gas from the generator if it will be stored for more than 30 days.

5. Is it safe to transport a Generac generator with gas in the tank?

No, it is not safe to transport a generator with gas in the tank due to potential spills and fire hazards.
