Brown Davis 145 Litre Auxiliary Long Range Fuel Tank Suitable For Ford Ranger Super Duty 2025 on - FRSD25A1

For owners of the Ford Ranger Super Duty who are serious about off-road touring, range and reliability are everything. That’s exactly where the new Brown Davis 145-litre auxiliary fuel tank comes into its own.

Designed to mount in the original spare wheel location, this tank makes smart use of space that many touring setups no longer need. With more drivers relocating their spare wheel to the rear of canopies or trays, the underbody cavity becomes the perfect home for extra fuel capacity—without compromising practicality or clearance.

This 145-litre auxiliary tank seamlessly integrates with the Ranger’s factory 130-litre tank, delivering a massive combined capacity of 275 litres. For those pushing even further into remote territory, it can also be paired with the Brown Davis 230-litre replacement tank, unlocking an enormous total of 375 litres onboard. That kind of capacity transforms long-distance travel, giving you the confidence to explore further between fuel stops.

Operation is simple and intuitive. At the push of a button, fuel is transferred from the rear auxiliary tank into the main tank, where it’s then used by the vehicle. A compact switch, fuel gauge, and buzzer unit can be neatly installed within the cabin for easy access and monitoring. Once the auxiliary tank has fully transferred its contents, the buzzer sounds—prompting you to switch off the pump and protecting the system from unnecessary wear.

Built from tough 2mm aluminised steel, the tank is engineered to handle the harshest conditions. It’s a natural match for the rugged capability of the Ranger Super Duty itself—two tough performers working together to take you further.

When your build is all about capability, endurance, and freedom, this setup delivers on all fronts.

Go further. Stay longer. Take on your longest journeys with total confidence—and no fuel worries.

Supplied with slim line twin filler. Fits into most tray mounting points.
