The purpose of two tanks
The Toyota Land Cruiser is an SUV with a variety of features, and some versions are equipped with two fuel tanks. This feature is commonly found on older models such as the Land Cruiser 80 Series (produced from 1990 to 1997) and certain variants of the Land Cruiser 70 Series.
The presence of two fuel tanks serves the purpose of increasing the vehicle's range and is especially useful in regions where accessing fuel may be challenging. The dual-tank setup effectively doubles the fuel capacity, allowing for extended travel distances without the need for frequent refuelling. This makes it beneficial for long-distance or off-road journeys.
Land Cruisers with two fuel tanks have a primary and secondary tank system. The main tank, being the larger of the two, holds most of the fuel, while the sub-tank is smaller. A switching mechanism or transfer pump allows the driver to select the tank from which fuel is drawn. This switch is conveniently located on the dashboard or centre console for easy access.
The dual-tank setup offers flexibility and peace of mind, especially when embarking on adventures in remote areas. It ensures that drivers can maximise their time exploring and minimise fuel-related concerns. The fuel gauge in the Land Cruiser also adds convenience by indicating the fuel level in both tanks, enabling drivers to monitor their fuel usage and plan their refuelling stops efficiently.
While the dual-fuel tank system is a notable feature in some Land Cruiser models, it is important to note that not all Land Cruisers, especially more recent models, are equipped with this feature. The availability of dual-fuel tanks can vary depending on the market, trim level, and regional specifications.

Fuel gauge functionality
The Toyota Land Cruiser is a large vehicle that, in some versions, comes equipped with two fuel tanks. This feature is more common in older models, such as the Land Cruiser 80 Series produced from 1990 to 1997 and certain variants of the Land Cruiser 70 Series. The dual-tank setup effectively doubles the vehicle's fuel capacity, making it ideal for long-distance or off-road travel, especially in regions with limited fuel availability.
The Land Cruiser's fuel gauge functionality is designed to indicate the fuel level in both tanks, allowing drivers to monitor fuel levels in each tank. This is achieved through a system that includes a sending unit and a gauge. The sending unit, located in the fuel tank, consists of a float connected to a thin metal rod and measures the level of fuel in the tank. The gauge then displays that level to the driver.
In the case of dual-tank systems, the Land Cruiser is equipped with a switching mechanism or a transfer pump that allows the driver to select which tank to draw fuel from. This switch is usually found on the dashboard or centre console. The gauge can indicate the fuel level in both tanks, but it reads the voltage drop across the sender resistance relative to 12v. This means that when one tank is full and the other is empty, the gauge will read full and display the value of the empty tank.
While fuel gauges are essential for monitoring fuel levels, they are notoriously inaccurate. They may show a full tank for the first 50 miles after filling up because the float is fully raised when the tank is full, and it won't start to sink until the fuel level drops. Similarly, the float may not reach the very bottom of the tank, resulting in the gauge showing an empty tank even with fuel still remaining. The shape of the fuel tank can also affect the accuracy of the gauge, as the float's position may not accurately represent the amount of fuel left due to the tank's shape.
To address the inaccuracy of fuel gauges, some drivers have suggested adding an indicator to show which tank is being read or manually switching the gauge to the second tank. Others have proposed using a ratio divider network or a simple circuit to switch the resistance the gauge sees based on the resistance of the second tank. These adjustments aim to provide a more accurate representation of the fuel levels in dual-tank systems.

Switching mechanism
The Toyota Land Cruiser is an iconic vehicle with a dedicated community of enthusiasts. While not all Land Cruisers have two fuel tanks, some variants do feature this setup, particularly older models. The dual-tank configuration was designed to extend the vehicle's range, making it ideal for long-distance or off-road journeys, especially in regions where fuel stations are scarce.
The switching mechanism is a crucial aspect of the dual-tank system. It allows the driver to select the fuel tank from which the engine draws fuel. This mechanism is typically located on the dashboard or centre console, providing easy access and control. The main tank is larger and holds most of the fuel, while the sub-tank is smaller and serves as a supplementary fuel source.
The switching mechanism is often accompanied by a transfer pump. This pump facilitates the transfer of fuel between the two tanks, ensuring a consistent and reliable fuel supply to the engine. The driver can use the switching mechanism to choose between the main and sub-tanks, optimising fuel usage based on their journey and fuel availability.
In some Land Cruiser models, such as the 200 Series, the factory setup includes a single fuel gauge that monitors the fuel level in both tanks. This gauge is fed by two sender units, one for each tank, providing an accurate reading of the overall fuel level. When the main tank is empty, the gauge will continue to show full until the fuel level in the sub-tank drops below a certain point.
Additionally, the Land Cruiser community has a range of options for aftermarket modifications. These include long-range fuel tanks offered by companies like Long Range America and Exitoffroad, which provide increased fuel capacity for extended journeys. These tanks may require exhaust modifications and can impact the accuracy of the fuel gauge, with low fuel warnings generally triggered at the same level as the original tank but with a greater reserve capacity.
The switching mechanism in the Toyota Land Cruiser's dual-tank system offers drivers flexibility and peace of mind, ensuring they can confidently embark on adventures both on and off the beaten path.
