Why Do Some Toyota Land Cruisers Have Two Tanks?

Certain Land Cruiser models, especially diesel variants in export markets, come with a dual fuel tank system: a main tank and a secondary sub tank.

Purpose of Two Fuel Tanks

• Extended Range – Crucial for remote areas with few fuel stations.
• Expedition-Ready – Supports overlanding and long-haul desert driving.
• Fuel Management – Allows for separate tank use or reserve fuel switching.
• Market-Specific – Common in Australia, Africa, and the Middle East.

The sub tank is typically smaller (20-45L), and fuel is transferred into the main tank via a dash-mounted switch or automatic pump system.
