An auxiliary (aux) fuel tank for your 4x4 vehicle is an additional fuel storage tank that supplements the main fuel tank. It’s typically installed to increase your driving range, especially useful for off-road adventures, remote travel, or towing.

Benefits include:
• Extended range: Travel longer distances without needing to refuel.
• Convenience: Fewer fuel stops, especially helpful in remote areas.
• Fuel management: Option to carry different fuel types or stock up where fuel is cheaper.
• Improved safety: Reduces the need to carry jerry cans externally.

It’s a great upgrade for overlanders and anyone exploring off-grid.
