Have you ever noticed your lawnmower sputtering, stalling, or struggling to start? A clogged gas tank could be the culprit. Over time, fuel can degrade, leaving behind varnish and sediment that can block fuel lines and prevent your mower from running smoothly. Cleaning your gas tank can be a simple solution to these issues, and it’s a task any DIY homeowner can tackle. In this comprehensive guide, we’ll walk you through the steps of cleaning a gas tank, from preparation to the final flush.
Understanding the Importance of a Clean Gas Tank
A clean gas tank is crucial for the efficient and reliable operation of your lawn mower. When fuel sits in the tank for extended periods, it can break down, forming gum and varnish that can accumulate inside the tank, fuel lines, and carburetor. This buildup can:
- Restrict fuel flow: The varnish and sediment can clog the fuel lines, preventing fuel from reaching the carburetor.
- Cause engine problems: The clogged fuel lines can lead to sputtering, stalling, and difficulty starting the engine.
- Damage the carburetor: The varnish can gum up the carburetor, requiring cleaning or even replacement.
Preparing for the Gas Tank Cleaning Process
Before you begin, it’s crucial to prepare the tools and equipment you’ll need. This includes:
- Safety Gear: Wear safety goggles to protect your eyes from potential splashes, and gloves to prevent skin contact with gasoline.
- Work Area: Choose a well-ventilated area to work on your lawn mower. Avoid working near any open flames or sources of heat.
- Tools: You’ll need a screwdriver, a wrench or pliers, a bucket or container, a funnel, a cleaning solution (gasoline tank cleaner or a mixture of gasoline and acetone), and rags.
- Disposal: Prepare a container for the used fuel and cleaning solutions. Ensure you dispose of them responsibly in accordance with local regulations.

Now that you’re ready, let’s delve into the step-by-step process of cleaning your lawn mower gas tank:
1. Drain the Old Fuel
H4. Safety First: Always disconnect the spark plug wire before working on the fuel system to prevent accidental ignition.
H4. Fuel Removal: Carefully remove the gas cap and use a siphon pump to drain the fuel from the tank. If you don’t have a pump, you can use a hose and gravity to drain the fuel into a container.
H4. Fuel Disposal: Dispose of the old fuel properly. Check with your local regulations for safe disposal methods.
2. Remove the Gas Tank
H4. Locate and Secure the Tank: Identify the gas tank, usually located on the side or top of the lawnmower. Use a wrench or pliers to loosen and remove any bolts or clips that hold the tank in place.
H4. Disconnect Fuel Lines: Disconnect the fuel lines from the tank. These lines usually have clips or clamps that can be released with a screwdriver.
3. Clean the Gas Tank
H4. Prepare the Cleaning Solution: Choose a gas tank cleaning solution from a reputable brand, or create your own by mixing gasoline and acetone (caution: this mixture can be flammable, so work in a well-ventilated area).
H4. Thorough Cleaning: Pour the cleaning solution into the tank, swirling it around to loosen and remove any debris. You can also use a brush or cloth to scrub stubborn deposits.
H4. Rinse Thoroughly: After cleaning, rinse the tank thoroughly with clean water. Repeat this process until all traces of cleaning solution are gone.
4. Dry the Gas Tank
H4. Drying Process: Allow the gas tank to air dry completely. You can also use a clean cloth to wipe out any remaining moisture.
5. Reassemble the Gas Tank
H4. Reconnection: Connect the fuel lines back to the tank, ensuring they are securely fastened.
H4. Reinstall: Reinstall the gas tank to the mower, tightening the bolts or clips.
6. Refill with Fresh Fuel
H4. Fresh Start: Pour fresh, clean fuel into the tank, avoiding any spillage.
7. Test the Lawn Mower
H4. Start Up: Reconnect the spark plug wire and try starting the lawn mower. If it runs smoothly, the cleaning process was successful.
Preventative Measures for a Clean Gas Tank
H4. Fresh Fuel: Use fresh, stabilized fuel in your lawn mower and avoid storing it for extended periods.
H4. Regular Cleaning: Clean the gas tank and fuel lines regularly to prevent buildup and ensure optimal performance.
H4. Fuel Stabilizer: Add fuel stabilizer to your gas tank during storage to help prevent fuel degradation.
Additional Tips
- Visual Inspection: Regularly inspect your gas tank and fuel lines for signs of rust or damage.

FAQ
What are the potential benefits of cleaning out a gas tank on a lawn mower?
Cleaning out a gas tank on a lawn mower can improve its performance and longevity. A clean gas tank ensures that the fuel system is free of debris and contaminants that can clog fuel lines, filters, and the carburetor. This results in smoother engine operation, better fuel efficiency, and reduced wear and tear on the engine. A clean gas tank also helps prevent the formation of varnish and gum deposits that can hinder fuel flow and cause engine problems.
How often should I clean out the gas tank on my lawn mower?
The frequency of cleaning your lawn mower’s gas tank depends on factors such as the age of the mower, the quality of the fuel used, and storage conditions. However, it’s generally recommended to clean it at least once a year, especially if you store the mower for extended periods. You should also consider cleaning the tank if you notice any performance issues like difficulty starting, uneven running, or reduced power.
What supplies do I need to clean out the gas tank?
To effectively clean out a lawn mower’s gas tank, you will need a few essential supplies. These include a suitable cleaning solution, such as carburetor cleaner or a dedicated fuel tank cleaner. You will also require a funnel for pouring the cleaning solution into the tank, a clean container to collect the drained fuel, and a rag or absorbent material for wiping up spills. A small brush or a piece of chain can be helpful for scrubbing stubborn debris from the inside of the tank.
What is the best way to remove the fuel from the tank?
The best way to remove fuel from a lawn mower’s gas tank is through a siphon. This involves inserting a siphon hose into the tank and using suction to draw the fuel out. Alternatively, you can use a small pump specifically designed for draining fuel. If you don’t have a siphon or pump, carefully pour the fuel into a clean container, taking care not to spill it. Remember to dispose of the fuel properly, as it is flammable.
Can I use water to clean out the gas tank?
Using water to clean out a gas tank is strongly discouraged. Water and gasoline do not mix, and introducing water to the gas tank can lead to serious problems. Water can corrode the tank’s interior, clog fuel lines, and potentially damage the carburetor. Always use a fuel-based cleaning solution specifically designed for cleaning gas tanks.
What should I do after cleaning the gas tank?
Once you have cleaned out the gas tank, it’s important to thoroughly rinse it with fresh gasoline. This will remove any remaining cleaning solution or residue. Allow the tank to air dry completely before reinstalling it on the lawn mower. After reinstalling the tank, ensure that all connections are secure and that the fuel lines are properly connected.
What should I do with the old fuel?
Old gasoline should not be poured down the drain or discarded carelessly. It is flammable and can harm the environment. The best way to dispose of old gasoline is to take it to a designated fuel recycling center or a local hazardous waste facility. They have the proper equipment and procedures to handle and dispose of fuel safely. You can also contact your local municipality or waste management agency for information on fuel disposal options in your area.
