LRA 40-gallon main tank installation
The LRA 40-gallon main tank installation process involves several steps and requires some technical knowledge. Here is a detailed guide on how to install the LRA 40-gallon auxiliary fuel tank in a 100 series vehicle:
First, it is important to note that the installation process may vary slightly depending on the specific vehicle model and year. In this guide, we will focus on the general installation process, which can be adapted to your particular vehicle.
Before beginning the installation, it is crucial to gather all the necessary tools and materials, including the LRA 40-gallon fuel tank, mounting hardware, hoses, and a suitable transfer pump. It is also recommended to have basic automotive repair knowledge and skills.
To start the installation, locate and remove the stock fuel tank from your vehicle. This step may involve some minor disassembly of surrounding components to access the fuel tank securely. Ensure you have a safe and environmentally responsible method for disposing of or recycling the old fuel tank.
Once the stock fuel tank is removed, you can prepare to install the new LRA 40-gallon tank. Start by lifting the new tank into position, carefully guiding the filler hose onto the steel filler line. Ensure that the fuel pump wire harness is positioned correctly over the frame rail to prevent any damage or pinching.
Next, secure the tank in place using the provided tank straps and reinforcing plates. Tighten the straps securely, following the manufacturer's instructions or torque specifications.
After the tank is securely mounted, you can proceed with connecting the necessary fuel lines and hoses. Attach the pressure fuel line and the fuel return line to the corresponding ports on the new tank. Ensure that all connections are secure and tight to prevent any leaks.
Additionally, install the supplied magnet in the new tank near the fuel pick-up, and install the fuel pump assembly. The assembly will only fit in one way, as the top of the tank is drilled in a specific pattern. It is recommended to use a new gasket during this step.
Finally, reinstall any components that were removed during the process, and ensure that all connections are secure and properly routed. Fill the new 40-gallon tank with fuel, and check for any signs of leaks before starting the vehicle. Refer to the vehicle's owner's manual or a trusted mechanic for specific post-installation instructions and safety checks.
Please note that this guide provides a general overview of the installation process. For detailed step-by-step instructions specific to your vehicle, it is recommended to refer to the installation manual provided by the manufacturer or seek guidance from a qualified automotive technician.

They provide a safe and leak-proof conduit for the fuel to travel from the auxiliary tank to the engine, ensuring your vehicle can utilize the additional fuel capacity effectively.
Installation Process:
During the installation process, you will need to carefully route the mounting hoses to establish a secure connection between the auxiliary tank and the fuel system. This may involve some creative hose routing, depending on the specific layout of your vehicle's engine compartment and fuel system. It is crucial to ensure that the hoses are securely clamped and fastened to prevent any leaks or disconnections while the vehicle is in motion.
Additionally, you may need to consider the placement of the transfer pump in relation to the mounting hoses. The pump should be positioned in a way that facilitates easy access for any future maintenance or repairs. Following the included instructions and consulting with professionals or experienced enthusiasts in online forums can provide valuable insights into the optimal routing of hoses and placement of the transfer pump for your specific vehicle.

EVAP canister and system
The EVAP canister and system are crucial components when installing an LRA auxiliary fuel tank in a 100 series vehicle. The EVAP (evaporative emission control) system prevents fuel vapours from escaping into the atmosphere by capturing, storing, and recycling them.
The installation process for the LRA auxiliary fuel tank involves careful consideration of the EVAP system. Firstly, you'll need to identify the location of the EVAP canister and ensure it is accessible and properly secured. The canister is typically located above the spare tire, and you may need to make adjustments to accommodate it, especially if you opt for the larger 40-gallon tank.
Before installing the auxiliary fuel tank, it is essential to inspect the EVAP system for any signs of damage or leaks. Ensure that the hoses and connections are intact and securely attached. Any damage to the EVAP system should be addressed before proceeding with the installation.
During the installation process, you will need to integrate the auxiliary fuel tank with the existing EVAP system. This involves connecting the tank to the EVAP canister and ensuring that the vapour recovery system functions correctly. The LRA auxiliary fuel tank should come with the necessary hoses and hardware for this step.
Finally, once the installation is complete, it is crucial to test the EVAP system to ensure it is functioning properly. Check for any leaks or blockages in the system and ensure that the vapour recovery process is effective. Regular maintenance and inspections of the EVAP system are essential to maintain optimal performance and prevent environmental harm.

Dual fill and fuel transfer
The LRA 24-gallon auxiliary fuel tank for the 100 Series Land Cruiser comes with instructions, a transfer pump (if applicable), and all mounting hoses and hardware. The installation process involves adding the auxiliary tank to the factory fuel tank, allowing for a dual-fill system.
The dual-fill system in the LRA setup allows for filling both the main and auxiliary tanks through the factory filler, eliminating the need to stop and refill fuel cans. This system improves the vehicle's range and lowers its centre of gravity. The electronic pump control in the dual-fill system is simple and functional, allowing for seamless fuel transfer between the auxiliary and primary tanks.
To manage the dual-fill system and fuel transfer effectively, it is essential to follow the provided instructions and ensure proper installation. The LRA dual-fill receiver plays a crucial role in this process, and any issues or queries regarding its usage can be directed to LRA's customer support. Their representatives, such as Ward and Kris, are noted to be helpful resources for addressing installation and usage concerns.
Additionally, customisation may be required to accommodate the evap and canister components above the spare tire. This customisation can be achieved by making a custom tank or relocating the spare tire to nest the auxiliary tank in the spare wheel bay, as seen in some user installations. It is recommended to consult with LRA or experienced individuals for guidance on managing dual-fill and fuel transfer setups, especially when encountering issues like overflowing EVAP or engine compartment evap tank floods.
