How Many Fuel Tanks Does a Land Cruiser Have?

A Toyota Land Cruiser can have either one or two fuel tanks, depending on the model, year, and market. Many standard consumer versions come with a single main tank, while certain heavy‑duty and expedition‑ready models feature a dual‑tank setup for extended range.

Single Tank Setup

Most modern Land Cruiser models, especially those sold in urban and developed markets like North America, come with one main fuel tank. This is sufficient for typical daily driving and highway use.

Dual Tank Setup

Some Land Cruiser models, especially those designed for remote travel or heavy‑duty work, have two fuel tanks…

• Main Tank – Feeds the engine directly.
• Sub (Auxiliary) Tank – Stores extra fuel and can be transferred to the main tank via a pump or selector valve.

Models Commonly Equipped with Dual Tanks

• 70 Series – Many variants in Australia, Africa, and the Middle East.
• 80 Series – Certain non‑U.S. models offered with a factory‑fitted sub tank.
• 100/105 Series – Available in some diesel and utility configurations.
• Special Utility Versions – Troop carriers, mining vehicles, and expedition builds.

Why Dual Tanks Are Used

Extended Range – Travel longer without refueling.

Remote Capability – Vital for areas with few or no fuel stations.

Fuel Management – Allows better control over weight distribution and fuel type use.
