Clean fuel is crucial to running your lawnmower smoothly and without any stutter. Additionally, it also ensures a long-lasting life of the mower’s motor. That’s why you will find fuel filters in most lawnmowers. These filters help keep the mower engine from becoming clogged by foreign substances in the fuel.
However, a worn-out filter will prevent fuel from reaching the carburetor, which may cause the engine to run rough or stop entirely. So, it is essential to remove the old fuel filter and replace it with a new one whenever you tune your riding mower.
Keeping this in mind, we will discuss the why’s and how’s of changing the fuel filter in a riding lawnmower. Stick with the article to learn about the details.
Where to Find the Fuel Filter of your lawnmower?
Before moving on to analyze the steps of changing the fuel filter of your mower, let’s understand where the filter is located in the mower.
In most cases, you can find the fuel filter located inside the fuel tank or the fuel line. But remember that some models of riding mowers come with non-replaceable internal filters.
That being said, if you are unsure about the location of the gasoline filter of your mower, look in the owner’s manual. You can also visit the website of the mower’s company to learn about its engine and fuel filter.
Why Change the Fuel Filter?
The next question that may hit your mind is why you should focus on changing the fuel filter of your mower every year.
Apart from the fact that a good fuel filter will help reach the fuel to the carburetor, the following are the benefits of changing an old filter.
1. Prolongs the Engine Life
A new and clean filter keeps dust at bay; otherwise, old filters harm the engine parts. By replacing these filters, you can avoid costly issues, like a breakdown. In addition, new filters prolong the engine’s life.
2. Increases Engine Power
As we stated, a gasoline filter enables clean fuel to enter the engine.
Moreover, it also allows the fuel delivery system to obtain the exact amount of fuel needed.
3. Improves the Mowing Performance
The gasoline filter prevents dirt and debris from entering the fuel supply system’s critical components. As a result, the engine’s performance improves.
4. Emission Reduction
A clogged and worn-out filter would discourage fuel supply to the fuel injectors, resulting in poor fuel burning and undesirable emissions. A new fuel filter will ensure that the engine receives the proper amount of gasoline and air, thus, minimizing any emissions.
