What You'll Learn
Removing the trailer hitch to access the fuel tank
If you decide to remove the trailer hitch, you will need to be prepared for potential challenges such as seized bolts or broken bolts. To address these issues, it is recommended to have a set of nut strips on hand and to soak the threads in a bolt loosener overnight. This will help to prevent the bolts from breaking and make them easier to remove.
- Use jacks to hold the vehicle in place while removing and reinstalling the bolts.
- Remove the straps, filler neck, and vent lines from the left side of the tank. These components are located under a protective cover that must be removed first.
- With the jack positioned correctly, the tank will drop straight down once the straps, filler neck, and vent lines are detached.
Removing the trailer hitch can be a complex and time-consuming task, and it may be advisable to seek assistance from a professional or a skilled technician if you encounter difficulties.

Disconnecting fuel lines
Disconnecting the fuel lines is a crucial step in removing the fuel tank from a Defender. Here is a detailed guide on how to approach this task:
First, it is important to note that different models of Defenders may have slight variations in their fuel systems, so it is essential to refer to your specific model's manual or seek guidance from experienced mechanics or online forums dedicated to Defender enthusiasts.
To begin disconnecting the fuel lines, you will need to access the fuel tank and identify the fuel lines connected to it. This may involve removing certain components, such as the trailer hitch or rear cross member, to gain better access to the tank. Ensure you have the necessary tools and safety equipment, such as gloves and eye protection, before starting.
Once you have clear access to the fuel lines, it is recommended to soak them in a penetrating lubricant like PB Blaster before attempting to loosen any connections. This will help prevent damage to the fittings and make it easier to undo them. Allow sufficient time for the lubricant to work as per the manufacturer's instructions.
Depending on your specific Defender model, you may need a special tool, such as the LRT-19-002, to disconnect the fuel lines safely. Refer to your manual or seek advice from experienced Defender mechanics or forums to determine the exact tools required. Some models may have unique fittings or connections that require specific tools for removal.
When you are ready to disconnect the fuel lines, place a container or rag underneath the connection to catch any residual fuel that may spill. Carefully loosen the fittings or clamps that secure the fuel lines to the tank. Use the appropriate tool, such as a line wrench or a fuel line disconnect tool, to avoid damaging the fittings. Slowly pull the fuel lines away from the tank, ensuring that they are completely disconnected.
After disconnecting the fuel lines, it is important to properly secure them to prevent fuel leakage or spillage. Use suitable clamps or caps to seal the open ends of the lines. Additionally, make sure to dispose of any spilled fuel or soaked rags properly, following local regulations and safety guidelines.

Removing the fuel filler neck
Firstly, it is important to note that removing the fuel tank and related components can be a complex process, and it is recommended to refer to the vehicle's service manual or seek assistance from a qualified technician. Ensure you are wearing appropriate personal protective equipment, including gloves and eye protection, and that you have a suitable workspace with adequate ventilation.
Begin by disconnecting the fuel lines. In some cases, a special tool, such as LRT-19-002, may be required to disconnect the fuel lines safely. However, some sources suggest that no special tools are necessary, and soaking the fuel lines in a penetrating solvent like PB Blaster before attempting to undo them should suffice. It is crucial to be gentle during this process to avoid damaging the gasket or paint.
Once the fuel lines are disconnected, you can focus on the fuel filler neck. Inspect the area around the fuel filler neck and identify any bolts or fasteners that secure it in place. Depending on your vehicle's specific configuration, there may be a combination of bolts, clamps, or other retaining mechanisms that need to be removed. Take note of their locations and the sequence in which they need to be removed.
Using the appropriate tools, carefully loosen and remove the bolts or fasteners securing the fuel filler neck. In some cases, you may need to use a wrench or a socket wrench to apply the necessary force. If the bolts are stubborn or difficult to access, you can try using a penetrating solvent again to help loosen them. Be cautious not to strip the bolt heads or damage the surrounding components.
With the bolts removed, the fuel filler neck should be free to be removed. Gently pull it away from the vehicle, being mindful of any attached hoses or wiring that may need to be disconnected or carefully manoeuvred to allow for sufficient clearance. Ensure you mark or label any hoses or lines to ensure proper reconnection during reassembly.
Finally, inspect the area where the fuel filler neck was attached for any signs of damage, corrosion, or leaks. This is also an opportunity to clean the surrounding area and inspect other components for any necessary maintenance or repairs. Ensure that you have a suitable plan for disposing of or recycling any old parts and fluids, and always refer to your local regulations and guidelines for proper disposal procedures.

Removing the fuel tank guard
Step 1: Disconnect the Fuel Lines
Before starting, it is recommended to soak the fuel lines in PB Blaster to make them easier to undo. This will help prevent any bolts from snapping during removal. Start by disconnecting all the fuel lines, hoses, and pipes from the fuel pump and tank. This includes the fuel delivery, breather, and any small pipes. Be careful not to damage the gasket or paint during this process.
Step 2: Remove the Trailer Hitch
One option to gain better access to the fuel tank is to remove the trailer hitch. However, this can be challenging if the hitch is rusty or tightly secured. If removal is not possible, you may need to pry the tank out, which can be done with the right tools and careful technique.
Step 3: Address Rust and Bolts
If the fuel tank cradle or bolts show signs of rust, consider media blasting, painting, or galvanizing to restore them. For stubborn bolts, you may need to use a liquid wrench or similar products to help loosen them. Be cautious when using power tools like grinders, especially if there are fuel fumes present.
Step 4: Remove the Fuel Tank Guard
With the fuel lines disconnected and access gained by removing the trailer hitch, you can now focus on the fuel tank guard. This step may require some force, but be mindful of the surrounding components. In some cases, you may need to remove the rear differential guard to gain those extra few millimetres of movement.
Step 5: Lower the Fuel Tank
Once the fuel tank guard is removed, you should be able to lower the fuel tank. It may drop down on one side, but if it doesn't, try pushing or pulling it in the opposite direction. Ensure you have adequate support to handle the weight of the tank.

Using a grinder to cut out joins
Removing the fuel tank from a Defender can be a challenging task and may require some specialised tools and knowledge. While there are various methods and approaches to removing the fuel tank, one common step is cutting out the joins using a grinder.
Before using a grinder to cut out the joins, it is important to take the necessary safety precautions. Ensure you are wearing appropriate protective gear, including eye protection, a respirator, and gloves. Work in a well-ventilated area or use a fume extractor to minimise the risk of inhaling harmful fumes.
The first step is to identify the joins that need to be cut. These are the points where the fuel tank is attached to the vehicle's chassis or other components. Place the grinder's blade on the join and start cutting through the metal. Use a steady and controlled motion, applying moderate pressure to ensure a clean cut. Take your time and avoid rushing, as this can lead to uneven cuts or damage to surrounding components.
It is important to use the right type of grinder and cutting disc for this task. A 9-inch grinder, as mentioned by a Defender owner, can be useful for reaching the joins over the rear cross member. Use a cutting disc that is suitable for metal and ensure it is in good condition to achieve a smooth and efficient cut. Have a few extra discs on hand in case the disc becomes worn or damaged during the process.
When cutting, it is essential to be mindful of the surrounding components and avoid causing any accidental damage. Place a piece of wood or a protective sheet behind the cutting area to prevent the grinder from accidentally cutting into other parts. Additionally, use wet rags to cover the fuel tank and surrounding areas to minimise the risk of sparks igniting any fuel residue.
After cutting through the joins, carefully lower the fuel tank and ensure it is securely supported. You may need to detach any remaining fuel lines or components still connected to the tank. Once the fuel tank is completely removed, you can proceed with your intended maintenance or repair work.
