If you're looking to remove the fuel tank from your John Deere LT155, you're in for a challenge. While it's not impossible, it's definitely a tricky task due to the lack of diagrams available for the tank mountings. The process involves loosening and lifting the fender deck, which is welded to the frame, and then carefully removing the fuel tank. Some people have managed to get the tank to rotate to the right and come out from under the right fender, but it requires patience and creativity. Additionally, there are bolts that secure the tank in place through tabs moulded into the tank and possibly a steel bracket.

What You'll Learn
Loosen the fender deck
To loosen the fender deck of a John Deere LT155, you will need to follow these steps:
Firstly, it is important to note that the process of removing the fuel tank from a John Deere LT155 tractor mower requires loosening and lifting the fender deck. However, it is unclear whether the fender deck can be completely removed, as some sources suggest that it is welded to the frame and cannot be removed or unbolted. Nevertheless, loosening it is necessary to access the fuel tank.
To begin loosening the fender deck, you will need to remove the rear guard, which is held in place by bolts that also secure the seat springs at the back. Depending on the model, there may be four to eight bolts securing the dash tower at the front of the fender deck. To access these bolts, you may need to remove the battery and battery tray first. In some cases, you may also need to remove the steering gear to lift the wheel and gain enough clearance to remove the dash tower.
Once the rear guard and dash tower have been removed, you can proceed to loosen the fender deck. It is recommended to refer to the official John Deere parts breakdown diagram to identify the specific bolts and components involved in securing the fender deck. This will ensure that you are safely and correctly loosening the necessary parts.
After loosening the fender deck, you should have improved access to the fuel tank and can proceed with the tank removal process. Remember to exercise caution and follow safety protocols when working with fuel systems and power tools.

Remove bolts
To remove the bolts from the fuel tank of a John Deere LT155, you will first need to loosen the fender deck. The fender deck is welded to the frame, so it cannot be removed or unbolted. However, loosening it will allow you to access the fuel tank.
Once the fender deck is loose, you can start to remove the bolts holding the fuel tank in place. The tank is held in with bolts that go through tabs moulded into the tank itself, as well as one or more steel brackets.
To access the bolts, you may need to remove or loosen other components, such as the rear guard, footboard plastic panel, seat, dash tower, and steering shaft. Unfortunately, John Deere no longer provides diagrams that show the tank mountings, so you may need to refer to other resources or seek assistance from a dealer or mechanic.
When removing the bolts, be sure to keep them organized and safe so that you can properly reinstall the fuel tank if needed. It is also important to note that the fuel tank may be connected to other components, such as fuel lines or hoses, which may need to be disconnected before completely removing the tank.
Always exercise caution when performing any maintenance or repairs, and ensure that you have the necessary tools and knowledge to complete the task safely.

Disconnect fuel line at fuel pump
To disconnect the fuel line at the fuel pump of a John Deere LT155 tractor, follow these steps:
- Locate the fuel line: The fuel line runs from the fuel tank to the fuel pump, which is located at the engine.
- Check for clogs: Before disconnecting the fuel line, it is important to check for any clogs or blockages that may be preventing fuel flow. You can do this by removing the fuel line from the carburetor to the filter and blowing into it. If you are able to blow through the line easily and hear fuel bubbling in the tank, the line is likely clear.
- Disconnect the fuel line: Once you have confirmed that the fuel line is clear, you can disconnect it from the fuel pump. Be sure to place a container underneath the connection to catch any fuel that may spill.
- Inspect the fuel pump: With the fuel line disconnected, you can inspect the fuel pump for any signs of damage or wear. Look for any cracks, leaks, or other issues that may be preventing the fuel from flowing properly.
- Replace the fuel line: If the fuel pump appears to be functioning properly, the issue may lie with the fuel line itself. In this case, it is recommended to replace the fuel line, as over time, the inside of the line can collapse, restricting fuel flow.
- Reconnect the fuel line: If you have replaced the fuel line or made any necessary repairs, reconnect the line to the fuel pump, ensuring a secure connection.
It is important to note that working with fuel and fuel lines can be dangerous, and it is always recommended to consult a qualified mechanic or technician if you are unsure about any part of the process. Additionally, be sure to work in a well-ventilated area and take appropriate safety precautions to avoid any accidents.

Blow air into the gas filler hole
To blow air into the gas filler hole of your John Deere LT155, first take off the fuel line at the fuel pump and put it in a cup or pail. Then, take an air hose and gently blow air into the gas filler hole, using your hand and a rag to seal the opening. The gas should start flowing out of the hose and into the cup or pail. This process will help to clear any blockages in the fuel line and ensure that gas can flow freely.
It is important to note that this process should be done with caution, as gasoline is highly flammable. Ensure that the engine is turned off and that all necessary safety precautions are taken before attempting to blow air into the gas filler hole.
Additionally, if you are experiencing issues with your John Deere LT155 not pulling gas from the fuel tank, there are a few other troubleshooting steps you can try. One suggestion is to rig up another tank and use it to gravity-feed the carburetor. If the engine cranks with this setup, then you know that the issue lies with fuel delivery.
Another possible solution is to check the fuel lines for any signs of collapse or degradation. Over time, the inside of the fuel lines can collapse internally, preventing fuel from flowing freely. In this case, replacing the fuel lines may be necessary.
Finally, if you are still experiencing issues, it may be worth consulting a professional mechanic or a John Deere dealer for further assistance. They will have the expertise and knowledge to diagnose and resolve any issues with your fuel tank or fuel delivery system.

Check for clogs
If your John Deere LT155 tractor is not getting fuel, there may be a clog in the fuel lines or fuel filter. To check for clogs, start by removing the line going from the tank to the fuel pump and observe if there is gas coming out. If there is no gas coming out, it indicates a potential blockage in the fuel line.
To further isolate the clog, you can use the fuel shut-off valve located at the bottom of your fuel tank to start and stop the fuel flow. Alternatively, you can use hose pinch-off pliers to clamp the line and control the flow. Check each section of the hose by starting and stopping the flow to identify the clogged section.
Once you've located the clogged section, remove the hose and spray carburetor cleaner into it to help loosen the clog. Follow this by blowing compressed air through the line to dislodge the clog. Repeat these steps until the clog is removed and the fuel line is clear.
If you are still unable to clear the clog or if the fuel line appears dry and cracked, it is recommended to replace the fuel line. Additionally, it is advised to replace your fuel filter annually as part of routine maintenance to prevent clogs and ensure optimal performance.
