A fuel pump is essential to keeping a push mower's engine running smoothly. If your mower is acting up, you should check its fuel system regularly to ensure there are no leaks or damage to the fuel tank cap and seal. To check the fuel line, locate the fuel valve and turn it off. If there is no fuel valve, clamp the fuel line to prevent gas flow. Disconnect the fuel line from the carburetor and turn on the power supply. If gas is not spurting out, the problem is likely with the fuel pump.

What You'll Learn
Locating the fuel pump
The fuel pump will be mounted on the mower, near the gas tank. It has two small rubber tubes connected to it. One connects to the gas tank, and the other to the engine's carburetor. On some mowers, the pump is powered by an electric current, so if you find an electric wire connected to the pump, it is likely to be one of these.
The fuel pump is typically mounted in one of four places: on the carburetor, near the fuel tank, or between the tank and the carburetor.
Before assuming that your mower's fuel pump is defective, you should perform a quick test. To do this, disconnect the fuel line from where it is connected to the mower's carburetor. Turn on the power supply and check to see if gas is spurting from the fuel line. If it is not, the problem is most likely in your fuel pump.
If you need to remove the pump, use a wrench or pliers, and a screwdriver. Be careful not to damage seals or gaskets.

Disconnecting the fuel line
To disconnect the fuel line on a push mower, you will first need to locate the fuel valve. This is often located at the base of the gas tank, where the fuel line meets the body of the tank. Once you have found the fuel valve, turn it to the "off" position. If your mower does not have a fuel valve, you can clamp the fuel line to prevent gas from flowing.
The next step is to remove the mounting screws and pump from the carburetor. Be careful not to damage any seals or gaskets during this process. With the pump removed, you can now access the fuel line.
Before disconnecting the fuel line, it is important to check for any signs of damage or leaks. Inspect the fuel hose carefully for any cracks, holes, or leaks. If you notice any damage, do not attempt to repair it. Instead, contact your local authorized dealer for assistance.
If the fuel hose appears to be intact, you can proceed with disconnecting the fuel line. To do so, simply detach the line from where it is connected to the carburetor. You may need to use a wrench or pliers for this step. Once the fuel line is disconnected, you can perform any necessary tests or repairs on the fuel pump or other components.

Checking for damage
To check for damage in your push mower's fuel line, start by locating the fuel valve and turning it to the "off" position. If your mower doesn't have a fuel valve, clamp the fuel line to prevent gas from flowing. Next, disconnect the fuel line from the carburetor and check for any damage. Look for cracks, holes, or signs of leakage in the fuel hose. If you notice any damage or leaks, do not attempt to repair the hose. Instead, contact your local authorised dealer for assistance.
It is also important to check the fuel pump for any damage. The fuel pump is located near the gas tank and has two small rubber tubes connected to it, one leading to the tank and the other to the carburetor. If the pump is defective, you may need to disassemble it and look for damaged, broken, or bent parts. Be careful not to damage the seals or gaskets during this process. Check for foreign matter such as sand or gasoline resin deposits, which can affect the pump's performance. If you find resin deposits, spray them with a resin solvent and let it sit for a few minutes to dissolve them.
Additionally, examine the fuel tank cap and seal to ensure they are not damaged. Check the engine regularly for any leaks and always exercise caution when handling fuel. It is recommended to perform these checks at the beginning of each season to ensure your mower is working optimally.
By following these steps and paying attention to the details, you can effectively check for damage in your push mower's fuel line and make any necessary repairs or replacements to keep your mower running smoothly.

Testing the pump
To test the pump, first, disconnect the fuel line from where it is connected to the mower's carburetor. You can locate the fuel pump by looking for two small rubber tubes connected to it. One of the tubes connects to the gas tank, and the other to the engine's carburetor. The pump will be mounted on the mower, near the gas tank. Next, turn on the pump's power supply and check to see if gas is spurting from the fuel line. If you can see fuel being pumped out, the pump is functioning correctly. If not, the problem may be in the fuel pump.
If the pump is not working, you will need to remove it from the mower using a wrench or pliers, and a screwdriver. Be careful not to damage any seals or gaskets. Once the pump is removed, carefully disassemble it by removing the screws that hold its parts together. Check the internal parts of the pump for any damage or foreign matter, such as sand or gasoline resin deposits, which could be causing the blockage. If you notice any resin deposits, spray the surfaces with a resin solvent and let it sit for about 10 minutes to dissolve the residue.
After cleaning or repairing the pump, follow the same procedure to test it again. If the pump is now functioning correctly, you can replace the fuel line and start the mower. If the pump is still not working, you may need to replace it.
It is important to familiarise yourself with the different components of your mower and perform regular checks on the fuel system to ensure optimal performance.
