What You'll Learn
Drain the tank
Before you begin, it's important to note that fuel and its vapors are extremely flammable and explosive, so always handle fuel with extreme care. If you are unsure of any procedure or have additional questions, see an authorized dealer.
Now, to drain the tank:
First, shut the fuel valve, if your tank is equipped with one. It may be located at the base of the fuel tank, where the gas line is attached. If your tank is not equipped with a valve, clamp the gas line using a fuel line clamp. Do not pinch the fuel line as this could cause damage.
Next, use a siphon or a fuel line cleaner to remove any fuel from the tank. This step minimizes spills. If your filter is installed inside the tank, you will need to drain the tank before you can remove the filter for inspection or replacement.
If your Briggs and Stratton engine is on a walk-behind mower, it may use a fuel filter located inside the tank at the fuel outlet. These cannot be replaced—consult your local Briggs dealers on how to service in-tank filters. A filter can also be located outside the tank, midway along the fuel line.
If your filter is installed in the fuel line, remove the metal clips on each side of the filter using needle-nose pliers, and slide the filter out of the fuel line. Shake the filter over a clean cloth to catch any dripping fuel.
Once the tank is drained, you can proceed to clean it.

Disconnect the spark plug
To clean a Briggs and Stratton fuel tank, one of the first steps is to disconnect the spark plug. This is a crucial safety measure to prevent accidental starts while you work on the engine.
Before you begin, gather your tools. You will need safety goggles, a screwdriver set, a wrench set, pliers, clean cloths, a wire brush, carburetor cleaner, and compressed air.
Now, locate the spark plug wire, which is attached to the spark plug. Using your screwdriver, carefully unplug the wire from the spark plug. Ensure that you do not apply too much force or use the wrong tool, as this could damage the wire or the plug. Once the wire is disconnected, set it aside in a secure place where it will not accidentally reconnect during the cleaning process.
It is important to note that disconnecting the spark plug wire is just one part of the process of cleaning your Briggs and Stratton fuel tank and carburetor. Other steps include draining the fuel, removing the air filter, and detaching the carburetor. Always refer to the engine manual for detailed instructions and safety precautions before attempting any maintenance or cleaning procedures.
By following these steps and taking the necessary precautions, you can safely disconnect the spark plug as part of the process of cleaning your Briggs and Stratton fuel tank.

Remove the air filter
To remove the air filter from your Briggs and Stratton engine, you will need to follow a few simple steps. Firstly, remove the air filter screw. You can do this with a screwdriver. Next, carefully remove the air filter assembly and discard the foam. It is important to clean all metal assembly parts at this stage.
Now, you will need to prepare your new foam filter. Saturate it with fresh engine oil and then wrap it in a clean cloth. Squeeze the foam to remove any excess oil. The next step is to assemble the new foam filter, ensuring that the lip extends over the edge of the body. Finally, you can reinstall the assembly carburetor.
It is important to note that a clean air filter promotes better airflow and enhances engine performance. Therefore, regular maintenance and cleaning of your air filter are crucial. Briggs and Stratton recommend replacing the pre-cleaner every 25 hours or every season, and the cartridge every 100 hours.

Detach the carburetor
To detach the carburettor, first, prevent accidental starts by disconnecting the spark plug wire from the spark plug. Next, drain the fuel from the tank using a siphon or a fuel line cleaner to minimise spills. Then, using a wrench or screwdriver, loosen the screws that connect the carburettor to the engine. Gently pull the carburettor away from the engine, being careful not to damage any fuel lines. Ensure that all fuel lines are disconnected before fully removing the carburettor.
It is important to note that fuel is highly flammable and explosive, so always exercise extreme caution when handling it. If you are unsure about any part of the process, consult an authorised dealer or a professional for assistance.

Clean and dry the tank
To clean and dry a Briggs and Stratton fuel tank, you must first drain the fuel tank. This can be done using a siphon or a fuel line clamp to minimise spills. If your tank has a valve, shut it off. If not, use a fuel line clamp to stop fuel flow.
Once the tank is drained, you can begin to clean the tank. Remove any debris and dirt from the tank. You can use a magnet to pick up any metal shavings. Then, wash out the tank and blow it dry. You can also swish a little dry gas around the tank and drain it. Ensure the tank is completely dry before reassembling.
If your fuel filter is clogged, you will need to replace it. Fuel filters can be found inside the tank or outside the tank, midway along the fuel line. If your filter is inside the tank, you will need to drain the tank before removing the filter. If your filter is outside the tank, simply remove the metal clips on either side of the filter using needle-nose pliers and slide the filter out. Replace the old filter with a new one, ensuring that the new filter is installed correctly.
Finally, before reassembling, check your fuel line for any signs of damage or decay. If the line is cracked, replace it.
