2023 Toyota HiLux aftermarket fuel tank guide

The further you go off the beaten track, the harder fuel is to come by.

This is why it's important rely on additional fuel-carrying capacity to get there and back, and where a high-quality replacement or auxiliary fuel tank comes into play. These provide additional capacity to travel in areas where fuel stops are few and far between.

• What it is: A replacement or auxiliary fuel tank to increase your fuel-carrying capacity. At present, the majority of legitimate options are replacement tanks, but auxiliary options do exist overseas so expect them to arrive in Australia in the future.
• Why you need it: When you start planning remote trips, you will quickly realise that fuel servos may be few and far between. Add that you’re probably driving on rough dirt roads or sandy tracks and the fact that you’re driving a modified vehicle that’s heavily loaded or towing a heavy trailer, and your fuel consumption will shoot up. This obviously brings your range from the factory fuel tank down even further. A replacement or auxiliary long-range tank is a simpler and easier option than carrying extra fuel in jerry cans.
• Buying tips: Ensure the fuel tank doesn’t hang lower than the chassis rails or reduce ramp-over angles, and that other components such as aftermarket exhausts and underbody protection and compatible with the tank. You may also need to recalibrate the fuel tank gauge.

Here are three products we recommend. They’re intended as a starting point, to give you an idea of what’s available.
