Brown Davis 175 Litre Replacement Long Range Fuel Tank for Toyota LandCruiser 100 Series IFS (Turbo Diesel & V8) & Lexus LX470 (1998–2007)

The Brown Davis 175 Litre Replacement Long Range Fuel Tank (TL100R3) is the ultimate fuel range upgrade for Toyota LandCruiser 100 Series IFS owners and Lexus LX470 drivers who demand the confidence to go further without compromise. Engineered and manufactured in Australia by Brown Davis — the country's most trusted name in long range fuel systems since 1978 — this tank replaces the factory 50 litre rear sub-tank, bringing your total fuel capacity to an outstanding 270 litres.

Constructed from high-grade aluminised steel and finished with a durable powder coat, the TL100R3 is built to withstand the harshest conditions Australia has to offer. With internal baffles to control fuel movement, a swirl pot to ensure every last litre is accessible, and seamless integration with the vehicle's factory fuel system, this tank is as practical as it is tough.

At Brixton 4x4, we stock the Brown Davis TL100R3 because we trust the engineering behind it. Whether you're crossing the Nullarbor, traversing Cape York, or heading deep into the High Country, this tank gives your LandCruiser 100 Series the range it deserves.
