Fuel pump issues
The fuel pump on a John Deere LX255 lawn tractor is bolted to the side of the engine block.
There are several issues that can arise with the fuel pump. Some customers have reported that the pump works well and fits perfectly, while others have experienced problems such as leakage, poor pump quality, and the pump failing after a short period of use.
One common issue is that the pump may not work with certain engines. For example, one customer reported that the new pump did not fix the issue with their tractor, and they discovered that the problem was actually caused by a chewed wire. Another customer reported that the pump flooded the carburetor, causing it to pump too much fuel.
Another issue that can occur is a cracked fuel line, which can prevent the fuel pump from pulling a vacuum. Any leak between the pump and the fuel tank will cause this issue, as the line must be vacuum-tight.
To replace the fuel pump on a John Deere LX255, the operator seat must first be lifted, and the wire on the seat switch disconnected from the wiring harness. The fuel line can then be disconnected from the top of the fuel tank, and the fuel tank can be lifted off the machine. The new fuel pump can be installed, taking care to install the inlet and outlet fittings before mounting, as well as depressing the release tabs to avoid damage to the o-rings.

Fuel line leaks
If your John Deere LX255 is leaking fuel, there are a few possible causes. Firstly, it is important to note that fuel leaks can be dangerous, so always consider your safety when inspecting a fuel leak. Engines can get extremely hot, and any excess fuel may combust, so turn off the tractor and let it cool before making an inspection.
One common cause of fuel leaks is when fuel drains back to the tank after the tractor has been sitting for a long period of time. Without fluid running through the fuel lines, they can become dry and crack, leading to leaks. Even with normal use, rubber fuel lines can deteriorate and form small holes.
Problems can also occur when changing the fuel filter. If the clamp is not tightened down tightly enough, or if it is over-tightened and breaks, this can prevent the fuel filter from holding a tight connection, leading to leaks.
If you suspect that your fuel line is cracked or damaged, you will need to replace it. John Deere dealers should have repair kits available to temporarily patch any leaks until the necessary parts can be replaced.
To access the fuel line on a John Deere LX255, first park the tractor on a level surface and set the parking brake. Then, lift the operator seat and disconnect the wire on the seat switch from the wiring harness. Remove the two 13 mm nuts just behind the seat that hold the fender deck to the frame. Pull out the mower adjustment knob in the middle of the fender deck, then remove the two 13 mm bolts under each foot pad. You can then lift the fender deck off, exposing the gas tank and fuel line.

Gas tank removal
To remove the gas tank on a John Deere LX255, follow these steps:
First, park the tractor on a level surface and engage the parking brake. Remove the key from the ignition and lift the operator seat. Disconnect the wire on the seat switch from the wiring harness. Next, remove the two 13 mm nuts just behind the seat that hold the fender deck to the frame with a socket wrench. Pull out the mower adjustment knob located in the middle of the fender deck, just below the operator seat.
Now, remove the two 13 mm bolts found under each foot pad on the fender deck. Lift the rear of the fender deck, and then pull it off to expose the gas tank. At this point, you should be able to access the fuel line and the gas tank.
Disconnect the fuel line from the top of the fuel tank using needle-nose pliers, and wipe up any spilled fuel. Pull the transaxle reservoir up and out from the right side of the gas tank. Now, you can lift the fuel tank off the machine and twist the fuel cap off. Place the fuel tank over a bucket and gently shake it to drain any remaining fuel.
Reinstallation is simply the reverse of this process. Ensure you are careful and methodical throughout, and refer to a professional mechanic or a detailed video tutorial if you are unsure about any steps.

Fuel hose
The fuel hose on the John Deere LX255 is part of the fuel system, which includes the fuel tank, fuel pump, fuel lines, and carburetor. The fuel hose connects the fuel tank to the fuel pump, allowing fuel to be drawn into the pump and delivered to the engine.
To access the fuel hose, you will need to remove the operator seat and disconnect the wire on the seat switch from the wiring harness. Next, remove the two 13 mm nuts just behind the seat that hold the fender deck to the frame. Pull out the mower adjustment knob in the middle of the fender deck and then remove the two 13 mm bolts under each foot pad. You can then lift and pull the fender deck to expose the fuel tank and fuel hose.
The fuel hose on the John Deere LX255 is typically a 1/4-inch diameter hose, and it can be purchased separately or as part of a fuel line repair kit. When replacing the fuel hose, it is important to ensure that all connections are secure and tight to prevent leaks.
In addition to the fuel hose, the fuel pump on the John Deere LX255 may also need attention. The fuel pump is bolted to the side of the engine block and has three lines coming off it: one from the gas tank, one going to the carburetor, and one going to the block or another place to access crankcase pressure. It is important to check that these lines are securely attached and not blocked or damaged.

Troubleshooting
If you are experiencing issues with your John Deere LX255 fuel line, there are several troubleshooting steps you can take to identify and resolve the problem.
Firstly, check your fuel pump, as low pressure may cause issues with the fuel line. The fuel pump is bolted to the side of the block and has three lines attached to it. One line comes from the gas tank, one goes to the carburetor, and the third goes to the block or another location with access to crankcase pressure. Ensure that the line accessing crankcase pressure is securely attached and not blocked.
Another potential issue could be a cracked fuel line or a leak between the pump and the fuel tank, preventing the fuel pump from pulling a vacuum. To resolve this, you may need to replace the fuel line.
If your LX255 is slow to start, there could be excess carbon buildup in the combustion chamber or a slightly dirty carburetor. To address this, you can use a product like Seafoam motor treatment, following the label directions. Basic maintenance, such as replacing the spark plug, air filter, and fuel filter, is also recommended. If your engine is an OHV, a valve adjustment may be beneficial.
Additionally, if your LX255 is not starting, you can try choking and moving a lever with a spring, located by the choke. Ensure that the fuel solenoid is receiving 12 volts and opening.
Finally, if you need to access the fuel line, you can do so by lifting the operator seat and disconnecting the wire on the seat switch from the wiring harness. Then, remove the two 13 mm nuts just behind the seat that hold the fender deck to the frame. Pull out the mower adjustment knob in the middle of the fender deck and remove the two 13 mm bolts under each foot pad. Lift the back of the fender deck, pull it off, and the fuel tank will be exposed.
