How to replace a fuel tank check valve
To replace a fuel tank check valve, you will first need to locate the fuel valve and turn it to the "off" position. The fuel valve is typically located at the base of the gas tank, where the fuel line meets the body of the tank. If your lawn mower does not have a fuel valve, you will need to clamp the fuel line to prevent gas from flowing.
Once the fuel flow has been stopped, you can begin the process of replacing the check valve. The specific steps may vary depending on the make and model of your lawn mower, but here are some general instructions:
- Drain the gas tank or use a tool like Vice-Grip pliers to pinch shut the hose close to the gas tank. This will help to prevent gas from flowing during the replacement process.
- Disconnect the old check valve from the fuel line. This may involve using tools like pliers, screwdrivers, or a socket set to remove the valve and any associated parts, such as a grommet.
- Clean the area and inspect for any damage, such as cracks or holes. If the fuel tank is compromised, it is important to replace it entirely for safety reasons.
- Prepare the new check valve by applying a small amount of oil to its surface.
- Insert the new check valve into the fuel line, ensuring that it is pressed firmly and aligned correctly. The arrow on the valve should point towards the carburetor.
- Secure the check valve in place using the appropriate connectors or clamps.
- Reattach any disconnected fuel lines or hoses, ensuring that all connections are secure and properly aligned.
- Once the new check valve is installed, inspect the fuel line for any debris, clogs, or damage. Replace the fuel line if necessary.
- Check for any fuel leaks and ensure that all connections are tight and secure.
It is important to consult the specific instructions for your lawn mower model and to have the necessary tools and safety equipment before attempting to replace the fuel tank check valve.

How to install a fuel tank check valve
Installing a fuel tank check valve in a lawnmower engine is a straightforward task that can be done at home. Here is a step-by-step guide on how to install one:
First, it is important to verify the size of the fuel line on your mower to ensure you get a valve that fits correctly. Most fuel lines are 1/4", but it is worth checking before purchasing a new valve. Once you have the correct valve, you can start by removing the air filter and its housing to access the fuel line easily.
Next, open the valve kit and locate the arrow on the valve, which indicates the direction of fuel flow. Ensure that the valve is added with the arrow pointing towards the carburettor. The valve fits inside the hose and will be secured with hose clamps.
At this point, the standard procedure is to drain the gas tank. If you have a full tank, you can use a pair of Vice-Grip pliers to pinch the hose shut close to the tank. Wrap the hose in a paper towel to protect it from the pliers' teeth. This will cut off the fuel flow from the tank, but there will still be gas in the hose, so have a small container ready to catch any spillage when disconnecting the hose from the carburettor.
Finally, install the new valve, reconnect the hose, and refill the gas tank with fresh fuel. You can now run the mower with the fuel shut off, and if you plan to store it for winter, remember to add a fuel stabiliser to the tank to prevent corrosion.
Some additional tools that may be helpful during the installation include snips or wire cutters, a utility knife, and a pair of pliers.
