Long-Range Fuel & Water

Go further between stops, carry water that lasts

Long-range tanks extend your driving range across remote country and let you carry the drinking water a serious expedition demands, without jerry cans on the roof.

Long-Range Fuel & Water

When the next fuel stop is six hundred kilometres away and you cannot count on it being open, factory range is not enough. A long-range fuel tank gives you the reach to cross remote tracks like the Canning, the Plenty or the Cape with a real safety margin, instead of strapping jerry cans to the roof rack where they raise your centre of gravity and pose a fire risk. We supply and fit quality long-range and auxiliary tanks engineered for the common touring platforms.

A replacement long-range tank swaps out your factory tank for a larger one, typically lifting a 79 Series, HiLux, Ranger or D-MAX from standard capacity to well over a hundred and fifty litres. An auxiliary tank adds a second tank that transfers or feeds into the main, which suits vehicles where a single replacement is not available. We help you choose based on your vehicle, your clearance and how you want the fuel managed, and we make sure the tank you choose is one with proven fitment and parts availability rather than a bargain unit you will struggle to service down the track.

Engineered to clear the tracks

A good tank is shaped and mounted to maintain ground clearance and departure angle, with steel or tough cross-linked polyethylene construction that shrugs off rocks and corrugations. We retain or relocate the factory protection, keep your spare wheel and exhaust clearances correct, and ensure the sender reads accurately so your gauge tells the truth. A tank that hangs low or fouls your recovery angles causes more problems than the range it adds.

  • Replacement long-range tanks for 79 Series, HiLux, Ranger, D-MAX and more
  • Auxiliary fuel tanks with manual or pump transfer
  • Accurate fuel sender calibration and dash gauge integration
  • Steel and cross-linked polyethylene construction options
  • Under-vehicle water tanks for self-sufficient touring
  • Clearance, departure angle and spare wheel retention preserved

Water you can rely on

Water is heavy and bulky, so carrying it under the vehicle keeps your centre of gravity low and frees up canopy space. We fit under-body or in-tray water tanks with food-grade construction, breathers and outlets, plumbed to a pump and tap so you have clean drinking water on tap at camp. For remote crossings we can combine fuel and water capacity to make your rig genuinely self-sufficient for a week or more away from any town. We can also add an inline filter and a gauge so you always know how much water you have left and that it is clean to drink.

Weight, balance and fitting it right

Extra fuel and water add real weight, so we factor it into your overall load and your GVM at the same time as we fit the tanks. A full long-range diesel tank can add over a hundred kilograms, and a full water tank plenty more, so we mount them low and central to keep your handling predictable rather than top-heavy. We protect the tanks with the existing or upgraded underbody guards, secure every line away from heat and chafe, and pressure test the install so there are no leaks on the first corrugated track. Done properly, the extra capacity changes how far you can go without changing how the vehicle drives.

The right capacity also changes which trips are even on the table, opening up remote loops and cut-through tracks that are simply out of reach on a factory tank. Range is peace of mind on a remote trip, and it is the freedom to take the long way around when the scenery is worth it. Tell us where you are headed and we will spec the fuel and water capacity that gets you there and back comfortably, with margin to spare.

FAQ

Long-Range Fuel & Water questions

It depends on the vehicle and your fuel use, but most replacement tanks roughly double your usable range. A 79 Series or dual-cab that managed eight hundred kilometres on a factory tank can often reach well beyond that on a larger tank.

A replacement tank is simplest and keeps one fuel gauge, while an auxiliary suits vehicles with no replacement option or owners who want to keep the factory tank. We recommend the best path based on what is available for your model.

Yes. We fit food-grade water tanks with proper breathers, outlets and mounting, plumbed to a pump and tap. Carrying water low and central keeps your handling stable and frees up storage compared with jerry cans.
