How to Drain Fuel from a Generator

Draining fuel from a generator is an important maintenance task that can prevent fuel deterioration and help keep your generator running smoothly when it’s not in use for extended periods. Follow these step-by-step instructions to properly drain your generator’s fuel. Remember to consult your generator’s manual for any specific instructions related to your model.

Safety Precautions

Before you begin, ensure you are taking adequate safety measures:

• Perform the task in a well-ventilated area, away from any open flames or sparks.
• Wear protective gloves and eyewear.
• Make sure the generator is turned off and cool to the touch.
• Disconnect the spark plug wire to prevent accidental starting.

Step 1: Run the Generator Dry

If your generator has a small amount of fuel and you prefer not to siphon, you can simply run the generator until it uses up all the fuel and turns off. This is the easiest method to ensure the fuel system is empty.

Step 2: Siphoning the Fuel

If there’s too much fuel to run the generator dry, you’ll need to siphon the fuel:

1. Locate the fuel tank and remove the fuel cap.
2. Insert the siphon pump’s tube into the fuel tank, making sure it reaches to the bottom.
3. Place the other end of the siphon pump into an approved fuel container.
4. Pump the siphon to begin transferring the fuel from the tank to your container.

Step 3: Draining the Carburetor

After siphoning out the fuel from the tank, it’s important to drain any remaining fuel from the carburetor:

1. Locate the carburetor’s drain bolt or screw, often found at the bottom of the carburetor bowl.
2. Place a container beneath the carburetor to catch the fuel.
3. Carefully unscrew the drain bolt or screw and allow the remaining fuel to drain into the container.
4. Once drained, re-tighten the drain bolt or screw securely.

Step 4: Dispose of or Store the Fuel Properly

Decide whether to dispose of the drained fuel or store it for future use:

• If disposing, transfer the fuel to a certified hazardous waste disposal facility.
• If storing, place the fuel in a properly labeled, sealed, and certified fuel storage container. Store the container in a cool, dry place away from direct sunlight and out of the reach of children.

Step 5: Reassemble and Test the Generator

With the fuel drained, you can now reassemble your generator:

• Reconnect the spark plug wire.
• Replace the fuel cap if it was removed.
• Start the generator following the manufacturer’s instructions to ensure it operates correctly. If you’ve completely drained the system, it may take a while for fuel to reach the carburetor again.

Keep these steps in mind not only for regular maintenance but also when preparing your generator for storage. Proper fuel management will extend the life of your generator and ensure it’s ready for use when you need it.
