What You'll Learn
Fuel filter location
The fuel filter location varies depending on the design of the engine. It is typically found along the fuel line between the fuel tank and the carburetor. If you are unsure of where your fuel filter is located, refer to your manual or an authorized dealer for guidance.
If your filter is installed in the fuel line, you will need to remove the metal clips on each side of the filter using a tool such as needle-nose pliers. Once the clips are removed, you can slide the filter out. If your filter is inside the tank, you will need to drain the tank before removing the filter.
When replacing the fuel filter, be sure to reconnect the metal clips on both sides of the new filter. Compress the fuel hose to prevent leakage and ensure that the new filter is installed in the correct direction, with the arrow pointing towards the engine.
It is important to note that some lawn mowers may not have a fuel filter. If you cannot locate the fuel filter, it is possible that your lawn mower engine does not have one.

Removing the fuel filter
Before removing the fuel filter, it is important to take some safety precautions. Ensure you are in a safe area with no open flame or fire source. Wear safety eyewear to protect your eyes from liquid fuel or fuel vapors. Have a dry cloth handy to hold the filter and catch any dripping fuel.
Now, locate the fuel filter. It is typically found along the fuel line between the fuel tank and the carburetor or fuel pump. If your filter is installed inside the tank, you will need to drain the tank before removing the filter. If your tank does not have a valve, clamp the gas line using a fuel line clamp. Do not pinch the fuel line as this could cause damage.
If your filter is installed in the fuel line, use pliers to loosen and remove the clamps or metal clips on each side of the filter, and then carefully slide out the filter. For canister-style filters, look through the transparent plastic casing and examine the pleated material inside for debris or severe discolouration. Tube-style filters should be inspected by looking closely at the meshed end for dirt or debris.
If your filter is dirty or clogged, it will need to be replaced. Rinsing the filter with clean gasoline or water and letting it dry before reinstalling is one option, but this is not recommended for canister-style filters as they are cheap and easy to replace.

Inspecting the filter
Inspecting the fuel filter is an essential step in maintaining your lawnmower. A functioning fuel filter ensures that your lawnmower's engine runs smoothly and efficiently. Here's a detailed guide on inspecting the fuel filter of your lawnmower:
Locate the Fuel Filter:
The fuel filter is typically found along the fuel line between the fuel tank and the carburetor. It could be inside or attached to the fuel line or inside the gas tank. The exact location varies from one lawnmower model to another.
Prepare for Inspection:
Before inspecting the fuel filter, it is crucial to take some preparatory steps for your safety and convenience:
- Safety First: Wear safety eyewear to protect your eyes from any exposure to liquid fuel or fuel vapors. This is an essential precaution when working with any combustible engine.
- Drain the Fuel Tank: If your fuel filter is installed inside the tank, you must first drain all the gas from the tank. You can do this with a siphon or simply run the mower dry outdoors.
- Disconnect the Spark Plug: Disconnect the wire from the spark plug to prevent any accidental starting of the engine while you work.
Inspecting the Fuel Filter:
- Visual Inspection: For canister-style filters, look through the transparent plastic casing and examine the pleated material inside. For tube-style filters, inspect the meshed end for any dirt or debris buildup.
- Check for Clogs: If you notice any debris inside the canister or severe discoloration, your filter is likely clogged and needs replacement. Tube-style filters should be rinsed carefully with water if they appear dirty; if not, they may need replacement.
- Shine a Light: Another way to check for clogs is by shining a light through the filter. If you cannot see light coming through clearly from the other side, it indicates that debris is clogging the mesh screen, pleated paper, or the inside of the casing.
Replacing vs. Cleaning:
If your fuel filter is severely clogged or discolored, it is best to replace it with a new one. Canister-style filters are challenging to clean, and it is more convenient and cost-effective to replace them. Tube-style filters can be rinsed with clean water and allowed to dry before reinstallation. However, if the tube-style filter is extensively clogged, consider replacing it.
Reinstallation:
After inspecting and cleaning or replacing the fuel filter, it is now time to reinstall it:
- Correct Direction: Ensure that the canister-style filter is installed in the correct direction, usually indicated by an arrow on the casing pointing in the direction of fuel flow. Tube-style filters should be oriented the same way as the old one.
- Reconnect the Fuel Line: Reconnect the fuel line and secure it with spring clamps or metal clips.
- Check for Leaks: Before starting the engine, check for any fuel leaks. If leaks are present, stop the engine, re-secure the hose and clamp, and consult a professional if needed.
By regularly inspecting and maintaining your lawnmower's fuel filter, you can ensure its optimal performance and prolong its lifespan.

Installing a new or cleaned filter
To install a new or cleaned fuel filter on your lawnmower, you will first need to locate the fuel filter. Typically, the fuel filter is found along the fuel line between the fuel tank and the carburetor. Once you have located the fuel filter, follow these steps:
Removing the Old Fuel Filter
Use pliers to loosen the clamps on either side of the fuel filter, then slide them away from the filter. Be careful when removing the filter, as you will need to inspect it.
Inspecting the Filter
Check the filter for dirt and debris. If it is clogged or dirty, it will need to be replaced. Even if you are cleaning and reinstalling the same filter, it is important to ensure that it is thoroughly cleaned and dried before reinstallation.
Installing the New or Cleaned Filter
If you are replacing the filter, install the new one in the same position as the old one. If you are cleaning and reusing the old filter, ensure it is completely dry before reinstallation. Slide the clamps back into place and make sure the filter is securely attached.
Final Checks
Once the new or cleaned filter is installed, check for leaks. If fuel is leaking, stop the engine immediately and re-secure the hose and clamp. Consult a professional for assistance if needed.
Remember to replace the fuel filter at least once a season or if you notice any signs of clogging. Always use the correct type of fuel filter for your specific lawn mower model. A functioning spark plug is essential for starting your lawn mower and keeping it running efficiently.

Reattaching the clamps
Ensure you have the correct clamps for your lawn mower model. Different models may require specific clamp sizes or types. It is important to use the correct clamps to ensure a secure and proper fit.
Before reattaching the clamps, it is essential to inspect the fuel filter and hose for any dirt or debris. If the filter is clogged, it should be cleaned or replaced. Refer to your lawn mower's user manual or seek advice from a qualified technician if you are unsure about the condition of the filter.
Now, slide the clamps back into position. Ensure that the fuel filter is securely attached by checking that the clamps are properly aligned and tightened. You can use pliers to carefully tighten the clamps if needed, but be careful not to overtighten them, as this can damage the clamps or the fuel line.
After reattaching the clamps, it is important to check for leaks. Start the engine and observe the fuel line and clamps for any signs of fuel leakage. If a leak is detected, immediately stop the engine and re-inspect your work. Ensure that the hose is not clogged and that the clamps are securely tightened. If the problem persists, consult an authorised service dealer for further assistance.
By carefully following these steps, you can confidently reattach the clamps when plugging your lawn mower's fuel line. Remember to take your time, use the correct tools, and always prioritise your safety when working with fuel lines and engines.
