Why Does the Land Cruiser Have 2 Fuel Tanks?
Purpose of Dual Fuel Tanks
Some Toyota Land Cruiser models are built with two fuel tanks to support long‑distance travel, especially in remote or off‑road environments where fuel stations are limited. This design maximizes range and self‑sufficiency.
Key Benefits
Extended Range
With two tanks, the vehicle can carry more fuel, often exceeding 130 liters. This allows for long journeys without needing to stop for refueling.
Off‑Road & Expedition Readiness
Dual tanks support travel through rugged or isolated areas where fuel access is unreliable or nonexistent. It’s especially useful for overland expeditions and commercial work.
Fuel Management
Drivers can manually switch between tanks or rely on automatic systems, helping manage weight distribution and fuel efficiency. It also serves as a backup in case one tank runs dry or has issues.
System Overview
The Land Cruiser’s dual‑tank setup usually includes…
- A main fuel tank and a sub-tank
- A transfer pump or switching mechanism
- Integrated gauges for fuel level monitoring
Fuel is either transferred from the sub tank to the main tank or drawn directly, depending on the model.
Designed for Utility
This system was originally developed for durability and function, not luxury. It supports the Land Cruiser’s core mission: reliability in demanding conditions. That’s why it’s commonly found in older 70, 80, and 100 Series models, especially those built for export or military use.
