Once you understand the type of fuel shut-off valve and have reviewed the manual, it’s time to physically locate the fuel tank or shut-off valve on your generator. Take your time and carefully inspect different parts of the generator until you find the proper component.

Using the Fuel Shut-Off Valve

Now that you’ve located the fuel shut-off valve, it’s time to learn how to use it effectively. Follow these steps to properly shut off the fuel supply to your generator:

Find and Turn the Fuel Shut-Off Valve

Locate the fuel shut-off valve on your generator and turn it to the “Off” position. Depending on the type of valve, you may need to twist, flip, or push/pull the lever or knob. Make sure the valve is fully closed to stop the fuel flow.

Keep a Container Ready

Before proceeding, have a container ready to collect the fuel that will be drained from the generator. Use a container that is suitable for holding gasoline and ensure it is clean and free from any debris or contaminants.

Let the Generator Run Until It Stalls

Once the fuel shut-off valve is turned off, start the generator and let it run until it stalls. This will help burn off any remaining fuel in the system and ensure a more thorough drain. It’s important to note that a generator may run for a short period before stalling, so be prepared for this when planning your fuel drainage task.

Draining the Fuel Tank

With the fuel shut-off valve turned off and the generator stalled, it’s time to drain the fuel tank. Follow these steps to successfully drain the tank:

Locate the Fuel Tank Drain

Locate the fuel tank drain on your generator. Depending on the model, there may be a drain plug or valve at the bottom of the tank. Consult your generator manual for specific guidance on finding the fuel tank drain.

Position a Container Under the Drain

Place your container directly under the fuel tank drain to catch the gasoline as it flows out. This will help prevent any spills or messes. Ensure that the container is clean and large enough to hold the expected amount of fuel.

Open the Fuel Tank Drain Valve

If your generator has a drain valve, use a wrench or pliers to open it. If there is a drain plug, unscrew it carefully. Be prepared for the fuel to flow out rapidly once the drain is opened. Keep a firm grip on the container to avoid any accidents.

Using a Siphon Pump

If you prefer to use a siphon pump to drain the fuel from your generator, follow these steps:

Prepare the Siphon Pump

Make sure your siphon pump is clean and in good working condition. Check that all the components are properly assembled and ready to use. Familiarize yourself with the pump’s instructions to use it effectively.

Insert the Pump into the Fuel Tank

Insert the siphon pump tube into the fuel tank, ensuring it reaches the bottom. A longer tube may be necessary for larger generators. Ensure the pump tube is securely inserted and will not come loose during the siphoning process.

Pump the Fuel Out

Once the pump is properly inserted, follow the manufacturer’s instructions to start the siphoning process. Pump the handle or activate the pump mechanism to create suction, which will draw the fuel from the tank into your container. Continue pumping until the tank is fully empty.

Using a Hand Bulb Pump

Alternatively, you may choose to use a hand bulb pump to drain the fuel from your generator. Here’s how to do it:

Acquire and Prepare the Hand Bulb Pump

Ensure you have a hand bulb pump that is compatible with gasoline. Familiarize yourself with the pump’s instructions and make sure it is clean and ready for use. Check that all connections and components are secure and tight.
