It’s a common scenario: your lawn mower has been sitting idle for the winter, or perhaps you’ve filled it with the wrong type of fuel. Now, you need to remove the old or incorrect gasoline. While a siphon is a common tool for this task, it’s not always readily available. This article explores several safe and effective methods for removing gas from your lawn mower without resorting to a siphon. Let’s delve into the techniques, precautions, and essential steps to ensure a smooth and spill-free operation.
Why You Might Need to Remove Gas from Your Lawn Mower
Understanding the reasons for removing gasoline from your lawn mower is crucial. Knowing why helps you choose the best method and take appropriate precautions.
Gasoline can degrade over time, especially when stored in an open or poorly sealed container like a lawn mower’s fuel tank. This degradation leads to the formation of gum and varnish, which can clog the carburetor and fuel lines, making it difficult, if not impossible, to start your lawn mower.
Using the wrong type of gasoline can also cause problems. For example, using gasoline with a high ethanol content in a lawn mower not designed for it can damage rubber and plastic components. Similarly, adding oil to a four-cycle engine’s gas tank can lead to engine problems.
Sometimes, you simply need to empty the fuel tank for maintenance or repairs, such as replacing the fuel filter or cleaning the carburetor. Storing your lawn mower for an extended period, particularly during the off-season, requires emptying the fuel tank to prevent fuel degradation and potential carburetor issues.
Essential Safety Precautions
Before attempting to remove gas from your lawn mower, prioritize safety. Gasoline is flammable and can be harmful if inhaled or ingested.
Work in a well-ventilated area, preferably outdoors, to avoid accumulating fumes. Ensure there are no open flames, sparks, or sources of ignition nearby. This includes pilot lights, cigarettes, and electrical equipment.
Wear appropriate personal protective equipment (PPE), including gloves and eye protection. Gloves will protect your skin from direct contact with gasoline, and eye protection will prevent splashes from entering your eyes.
Have a spill kit readily available. This should include absorbent materials like rags or paper towels to clean up any spills immediately. Also, have a container designated for storing the used gasoline.
Never smoke while handling gasoline. Keep children and pets away from the work area to prevent accidental exposure to gasoline.
Methods for Removing Gas Without a Siphon
Several methods exist for removing gasoline from a lawn mower without using a siphon. Each method has its advantages and disadvantages, so choose the one that best suits your situation and lawn mower model.
The Tipping Method
The tipping method is perhaps the simplest, but it requires caution to avoid spills. This method is best suited for lawn mowers with a fuel tank located at the bottom.
First, ensure the lawn mower is cool and has been turned off for at least 15 minutes. Disconnect the spark plug wire to prevent accidental starting.
Carefully tilt the lawn mower so that the fuel tank opening is facing downward. Position a suitable container, such as a gas can, beneath the opening to catch the gasoline.
Hold the lawn mower firmly and slowly tilt it until the gasoline begins to flow out. Control the flow to minimize spills.
Once all the gasoline has drained, carefully return the lawn mower to its upright position. Use absorbent materials to clean up any spilled gasoline.
The Fuel Line Disconnection Method
This method involves disconnecting the fuel line from the carburetor and allowing the gasoline to drain out. This method provides more control than the tipping method.
Locate the fuel line connecting the fuel tank to the carburetor. It is usually a small rubber hose secured with clamps.
Place a container beneath the fuel line connection to catch the gasoline. Use pliers to carefully loosen the clamp securing the fuel line to the carburetor.
Gently detach the fuel line from the carburetor. The gasoline will begin to flow out of the fuel line.
Allow the fuel tank to drain completely. Once drained, reattach the fuel line to the carburetor and secure it with the clamp.
The Carburetor Drain Plug Method
Some lawn mowers have a drain plug on the carburetor that allows you to drain the fuel bowl. This is a controlled and relatively clean method.
Locate the carburetor drain plug. It is usually a small screw or bolt located at the bottom of the carburetor.
Place a container beneath the drain plug to catch the gasoline. Use a wrench or screwdriver to loosen and remove the drain plug.
Allow the gasoline to drain completely from the carburetor’s fuel bowl. Once drained, reinstall the drain plug and tighten it securely.
Using a Turkey Baster or Large Syringe
If you only need to remove a small amount of gas, a turkey baster or a large syringe can be surprisingly effective. This method is useful for removing small amounts of contaminated gas.
Insert the turkey baster or syringe into the fuel tank. Draw the gasoline into the baster or syringe.
Carefully transfer the gasoline into a suitable container. Repeat until you have removed the desired amount of gasoline.
This method is particularly useful for removing small amounts of gasoline that may have become contaminated or degraded.
Fuel Pump Method (If Equipped)
Some lawn mowers, especially those with larger engines, have a fuel pump. You can use this pump to remove the fuel. This method is efficient for mowers with a functioning fuel pump.
Locate the fuel line after the fuel pump, leading towards the carburetor. Disconnect this line, placing a container underneath to catch the fuel.
If the mower has an electric fuel pump, briefly turn the ignition key to the “on” position (without starting the engine) to activate the pump and drain the fuel. For mechanical fuel pumps, you may need to manually operate the pump lever.
Continue pumping until the tank is empty. Reconnect the fuel line after completion.
Dealing with the Old Gasoline
Once you’ve removed the gasoline from your lawn mower, you need to dispose of it properly. Never pour gasoline down the drain or onto the ground.
The best option is to take the used gasoline to a hazardous waste collection center or a local recycling facility. These facilities are equipped to handle gasoline safely and environmentally responsibly.
If you can’t take the gasoline to a recycling facility, you might be able to reuse it in another gasoline-powered engine, provided it’s relatively clean and hasn’t degraded significantly. Add a fuel stabilizer to the gasoline to help prevent further degradation. However, it’s generally not recommended to use old gas in high-performance engines.
Preventive Measures
Preventing the need to remove gasoline from your lawn mower in the first place is always the best approach. Implementing preventive measures saves you time and hassle.
Always use fresh gasoline and add a fuel stabilizer when storing your lawn mower for extended periods. A fuel stabilizer will help prevent the gasoline from degrading and forming gum and varnish.
If you know you won’t be using your lawn mower for several months, drain the fuel tank completely before storing it. This is especially important during the winter months.
Store your lawn mower in a dry, well-ventilated area. Protect it from extreme temperatures and direct sunlight, which can accelerate fuel degradation.
Regularly inspect your lawn mower’s fuel system for leaks or damage. Replace any worn or damaged components promptly.
Consider using ethanol-free gasoline in your lawn mower, especially if it’s an older model. Ethanol can damage rubber and plastic components in some engines.
Troubleshooting Common Issues
Even with careful planning, you might encounter problems while removing gas from your lawn mower. Knowing how to troubleshoot common issues can save you time and frustration.
If the gasoline isn’t flowing freely, check for obstructions in the fuel line or carburetor. A clogged fuel filter can also restrict fuel flow.
If you spill gasoline, clean it up immediately with absorbent materials. Avoid using water, as it will only spread the gasoline.
If you accidentally get gasoline in your eyes or on your skin, rinse thoroughly with water. Seek medical attention if irritation persists.
If you are having difficulty removing the fuel line, use a specialized fuel line removal tool. This tool will help you disconnect the fuel line without damaging it.
