What You'll Learn
Fuel pump issues
The John Deere X500 is a lawn tractor that has been known to have fuel pump issues. Users have reported that the tractor stalls while mowing, and in some cases, the engine won't turn over at all.
There are several potential causes for these issues. One common problem is a clogged fuel line or fuel pump. Over time, debris can build up in the fuel system, leading to blockages that prevent fuel from reaching the engine. This can be remedied by disassembling the fuel system, cleaning or replacing the fuel lines and filter, and ensuring that there is no debris in the tank.
Another potential issue is a cracked fuel line. Even a small hole or crack can allow air into the line, preventing the pump from effectively delivering fuel to the engine. Inspecting the fuel and vacuum pulse line for any signs of damage is essential.
In some cases, the fuel pump itself may be faulty. If there is no gas in the lines and the fuel filter is dry, it could indicate a problem with the pump. To test this, users can try pressurizing the fuel tank by blowing into it or using an air compressor with a blow gun. If gas does not flow through the lines after pressurizing the tank, it likely indicates a faulty fuel pump that needs to be replaced.
Additionally, it is recommended to use a fuel stabilizer in the tank, especially when storing the tractor for extended periods, such as over the winter. This can help prevent issues with condensation and ethanol fuel buildup in the carburetor, which can lead to expensive repairs.
Overall, while the John Deere X500 is generally well-regarded, users should be aware of potential fuel pump issues and take proactive steps to maintain their tractor's fuel system to ensure optimal performance.

Clogged fuel lines
If your Deere X500 won't start, there could be no gas in the lines and the fuel filter could be dry. To fix this, you can try the following:
Check for cracks or holes in the fuel lines
Firstly, look over all the fuel lines starting from the engine, then work your way back to the tank. There could be a crack or small hole allowing air into the line, so the pump can't bring the fuel to the engine.
Check the fuel pump
If the fuel lines are intact, the issue could be a clogged or faulty fuel pump. To test this, disconnect the fuel line between the fuel filter and the gas tank. If no fuel comes out, blow air towards the gas tank. If you can hear air bubbles in the tank, it is not blocked. Try pouring some gas directly into the carburettor intake. If the engine starts and then dies when the gas runs out, the fuel pump may be defective.
Clear the fuel line
If the fuel pump is working, the fuel line could be clogged. To clear it, remove the fuel line from the filter to the carburettor, clean it with air, then reconnect the fuel line. Before cranking, remove the battery connections and clean the terminals. Check the battery voltage and charge it if necessary.
Preventative measures
To prevent clogging, it is recommended to fill metal tanks with premium fuel and a stabilizer such as Sea Foam for the winter. This leaves less air space to allow condensation, which can cause rust to form and clog the fuel lines and filters.

Fuel tank problems
The fuel tank on the John Deere X500 lawn tractor has a capacity of 4.4 gallons. The fuel tank and all other X300 and X500 series fuel tanks are made of plastic.
Some common problems with the fuel tank on the Deere X500 include:
- Water in the fuel tank: Water in the fuel tank can cause the tractor to crank but not run. To resolve this issue, drain the fuel/tank/carb, let the tank dry out, replace the fuel filter, and refill with fresh gas.
- Clogged fuel line: A clogged fuel line can be caused by debris at the bottom of the tank. This can be resolved by blowing air through the line into the tank to dislodge the debris.
- Cracked fuel line: A cracked fuel line can allow air into the line, preventing the pump from bringing fuel to the engine. Inspect the fuel and vacuum pulse line for any cracks or holes.
- Fuel pump issues: The fuel pump may be clogged or faulty, preventing gas from reaching the engine. This can be diagnosed by blowing air into the fuel tank and observing if gas shoots out of the hose.
- Plastic chips in the tank: Plastic chips left in the tank during manufacturing can cause issues over time.

Fuel filter issues
The fuel filter is one of the most important components of the John Deere X500. If it becomes clogged, it can cause the engine to run poorly or not start at all.
To fix this issue, you will need to replace the fuel filter. If you notice that your tractor is stalling, check the fuel filter and spark plugs. If they are dirty, replace them. If that doesn't fix the problem, take your tractor to a John Deere dealer for service.
One of the most common issues with the John Deere X500 is that the engine stalls while mowing. This can be caused by a clogged fuel filter, a bad fuel pump, or a problem with the fuel solenoid. If your tractor is not getting enough fuel, it may be necessary to replace the fuel pump and filter.
If your tractor has been sitting for a long time, there may be no gas in the lines and the fuel filter may be dry. In this case, you should inspect the fuel lines for any cracks or holes that could be allowing air into the line and preventing the pump from bringing fuel to the engine. It is also possible to pressurize the fuel tank by blowing into it to check for clogs.
Another potential issue is condensation forming inside the fuel tank during winter, which can lead to rust and clogging in the fuel lines and filter. To prevent this, some owners choose to fill their tanks with premium fuel and stabilizer for the winter.

Fuel line size
The fuel line size for the John Deere X500 lawn tractor is not specified in any of the sources. However, it is mentioned that the X500 model was discontinued in 2015, and the newer models, such as the X570, X580, X584, and X590, have a fuel tank capacity of 4.4 gallons.
Now, when it comes to fuel line size, it is important to distinguish between the hard metal lines and the rubber fuel lines that connect them. The hard lines are typically made of metal and are more rigid, while the rubber lines provide flexibility and are used to connect the hard lines to other components of the fuel system.
For tractors with small engines, a common fuel line size is 1/4-inch inner diameter (I.D.). However, some tractors, like the Ford 5000, may have a mix of line sizes. For example, it can have a 1/4-inch line coming out of the fuel shut-off valve, which then transitions to a 5/16-inch line going into and coming out of the fuel pump. The Ford New Holland online parts book specifically mentions that the Ford 5000 uses 5/16" lines.
When replacing or repairing fuel lines, it is important to use the correct size to ensure proper fuel flow and engine performance. It is also worth noting that some tractors, like the John Deere 455 with a Yanmar diesel engine, may use a 5/16-inch fuel line, which is different from the standard size for small engines.
In the case of the X500, since it is a lawn tractor, it likely falls into the category of small engines. Therefore, a 1/4-inch fuel line size or a mix of 1/4-inch and 5/16-inch lines, similar to the Ford 5000, could be a possible configuration. However, without specific information for the X500, it is challenging to provide an exact answer.
