How to drain gas from Lawnmower without Siphon (Step-by-Step)

In this guide, we will show you how to drain gas from a lawnmower without a siphon. It is a good idea to empty the mower gas tank before storing the lawnmower at the season’s end. It prevents the accumulation of dirt and blockage in the fuel injection system. This avoids serious problems, mostly in lines, such as corrosion or leakage.

Moreover, if the lawnmower didn’t start after a long duration, it might be faulty gas. Don’t worry if you don’t even have a siphon to draw out the gasoline; we’ll show you how to empty the tank with common household items.

Step-by-Step instructions for draining gas from a lawnmower without using a siphon

  1. Gather the necessary equipment.

    A gas-resistant drainage container is the first equipment you’ll need to empty gas. If you don’t have an emptied container, you could use a drainage dish. The drainage dish is a compact steel dish with high sides that collects and handles the gas.

    After that, you’ll require a drainage tube. It’s preferable to have two basic plastic pipes on hand that can be obtained at most mower supply shops. Get some towels ready as well.

  2. Park your lawnmower in and remove the plug.

    Place the lawnmower on a level, sturdy surface. To prevent it from rolling, use handbrakes. It’s a wise move to unplug the plug wires as a precaution. This will prevent the motor from starting by accident. Close the gasoline tank and switch off the engine.

  3. Ensure that the tubes/hoses are appropriately positioned.

    You’ll need two PVC tubing/hose parts if you don’t have a siphon. It’s best if they’re transparent. Make sure the length can reach the fuel tank from containers; another might be short. Put the emptied drainage container on the floor near to lawnmower’s fuel tank. Ensure the lengthier pipe or hose is fully immersed in the gasoline in the lawnmower’s fuel tank. It’s preferable if it touches the tank’s bottom. The tube appears to be in contact with the tank’s bottom.

    Next, insert the larger tube’s end into the drainage container. Insert the short pipe into the fuel tank a few feet so that the tubes are parallel. On the other hand, the short pipe must not come into contact with the gas within the tanks. Its primary goal is to provide an air route between the tanks and the surrounding environment.

    Then, the gasoline lid through which pipes are placed must be sealed. The goal is for air to flow solely through a short pipe within. It will aid in forming an air pressure difference that would force the fuel outside. To secure the attachment, you can use a damp cloth. The damp towel is utilized because it adheres well.

  4. Remove the tank and empty it.

    You’re all ready for the exhausting work now. You’ll have to produce a propelling pressure to push the fuel outward. Blow vigorously into the short tube’s wide end to force air into the container. The procedure gets significantly easier if you have availability for an air compressor or pump. Use it to push air into the container and ensure the container entrance is covered with a towel. When puffing in the container, ensure you don’t breathe any petrol vapors.

    After several blows, you’ll see that gas begins to flow out from the container through another pipe. You can cease blowing whenever the stream becomes constant. The remainder is taken care of by gravitational and atmospheric differences. All the gas will be emptied.

  5. Remove the carburetor’s attachments and, if applicable, remove the tube.

    You get two alternatives for removing the residual gasoline from a lawnmower. Empty the gas from the engine or use the lawnmower when it is completely depleted.

    Disconnect the gasoline line between the engine and the gas tank to empty the mower’s gas. It seems to have some petrol in it. Allow it to flow into a drainage pipe below the container. Most mowers get a drainage pipe at the tank’s bottom, and some have a drainage valve that eventually meets the engine’s container. You may also drain liquid fuel by removing the container and allowing it to drop into a dish below it.

  6. Let the lawnmower operate for a few minutes.

    Cover the container after removing the pipes from the aperture. Since gas is extremely flammable. It should be saved for further usage. You’ll note that the container always has a tiny quantity of gas remaining in it. It still is a good decision to drain the fuel tank if you’re keeping the lawnmower for an extended time, such as in the wintertime. Start the engine. Put the mower outdoors and operate till the fuel runs out and the motor stops. You’ll have emptied all the gasoline at this point.

Preventive Measures

A lawnmower must not be used in a closed space. The odorless, colorless carbon monoxide gas found in diesel exhaust is dangerous, hazardous, and can affect health. While examining a mower, it is recommended that one should do so outside.

Assume you’re using a workshop to operate the lawnmower. In that scenario, it is only used for a brief period, and appropriate ventilation must be maintained at all times.

When working with gasoline, you must always disconnect any sources that might cause a spark or ignite.

Conclusion

In this article, we’ve listed all the necessary equipment that one might need to drain the gas from a lawnmower without a siphon. These items are easily accessible, and you can do it by yourself at home. Now, that you know how to drain gas from a lawnmower without a siphon, you can do it yourself!
