How to Clean a Gas Tank on a Lawn Mower? The primary purpose of Lawnmowers fuel tanks is to store gas, but they are also necessary to keep your engine’s fuel clean, secure, and vented. If you haven’t used your lawnmower in a long time, it may fail to start when you try to mow your lawn. This is primarily due to the residual fuel in the tank. A blocked fuel line can also be caused by debris, old fuel, or condensation. If you notice debris or dust in the gas tank, or if gas is leaking. It is time for fuel tank maintenance.

How to Clean a Gas Tank on a Lawn Mower

Step 1: Inspect the spark plug:
The spark plug is one of the most important and fundamental components of a gas tank. A spark plug is essential for keeping your engine running by igniting the air-fuel mixture during combustion. The plug is made up of two leads that form an electric arc, which produces the spark. Carbon buildup can have an effect on spark generation over time. Furthermore, wear and tear can cause the electrode to weaken.

– Spark plug inspection: Inspecting the spark plug for damage or wear and tear should help you determine whether or not the component is working. Check to see if there is any significant carbon buildup or if any electrodes are broken.

– Ignition tester: Use an ignition tester to see if the plug is producing a spark. The terminals of the tester will show a vital spark, indicating that the component is working properly. No spark indicates that the plug is faulty and must be replaced.

– Replacing the plug: A faulty spark plug cannot be repaired. New spark plugs are inexpensive and can make a significant difference in engine performance. As a general rule, you should replace your spark plug once a year.

This is just an extra precaution in case some vapours remain that are sufficient to start the engine and rotate the blade while cleaning the lawnmower as the tank. Do not use the attached spark plug to clean the mower.

Step 2: Drain the tank:
Before you begin, prepare the gas container. Now, disconnect the fuel line from the carburetor. Place the gas container beneath the tank and drain the gas. When the tank is empty, use the flashlight to look for debris and light beads that will reveal cracks or holes. To remove slack debris, use a baster. If damage is discovered, substitute or replace the tank with original manufacturer’s equipment.
Step 3: Clean the carburetor:
The carburetor is an important component that provides the correct air-fuel mixture and leads up to the combustion chamber. Clogging can cause the pipes to thin out, resulting in insufficient fuel. In extreme cases, the engine power drops dramatically and begins to gurgle.

Step 4: Rinse the tank: Never wash the tank with water. Residual water can cause problems with fuel carburetors or injectors. Alternatively, rinse the tank with a small amount of gas. Close the tank and shake it vigorously so that the gas can thoroughly clean the inside of the tank. Pour the used gas into the old gas can. This used gas could not be used in other operational engines because it would clog or damage them. Dispose of all old and unused fuel in a secure manner.
Step 5: Inspect the fuel filter for dust and deposits:
The oil or fuel filter is the last line of defence before the fuel enters the combustion process. As the name implies, the filter is in charge of removing impurities, dirt, and potentially harmful objects such as insects and residues while allowing only fuel to pass through. If contaminated fuel comes into contact, the filter may become clogged and cease to function well before its expected life. As a result of all of this, the engine action becomes rough, resulting in cranking issues.

When applying pressure, it is always preferable to use clean fuel with fuel stabilisers. Extra fuel in the tank is always a source of contention.
Fuel filters, like all filters, should be replaced once a year unless the black residue is visible to the naked eye.

Step 6: Replace the fuel tank:
Reattach an old fuel tank or instal a new one, and tighten the cap screws firmly. It is now safe to replace the filter and fuel line. Never attempt to overhaul a damaged tank. It is prone to leaks, fuel contamination, and fires. To maintain the pressure difference between the environment and the fuel system, many tanks employ a vented gas cap. If the fuel is leaking, a properly fitted back up cap can fix the problem.
Final Thoughts:

Purchase smaller quantities of gas in the future to ensure that you are using high-quality gas. I will decay if the gas remains for an extended period of time. Purchase only enough gas to last two to four weeks. Add a fuel stabiliser to your mower before going on an extended vacation to prevent fuel degradation. When you’re mowing, try to keep the throttle open to help us get rid of all the fuel before putting it back in the shed. When you do this on a regular basis, the gas in the tank will not stale. Stale gas corrodes the tank, damages rubber lines, and produces debris and junk that destroys carburetors.
