Long Range Fuel Tanks

What a Long Range Fuel Tank Actually Is

There are a few ways to add fuel capacity to a truck. In-bed auxiliary tanks, jerry can mounts, portable transfer setups. But a long range replacement tank is a different thing entirely. These units mount in the same underbody position as your factory tank, using the same mounting points and connections. No cargo space is sacrificed, nothing sits in your tub, and nothing interferes with your tow hitch or accessories. They're not a workaround. They're a proper upgrade.

The tanks we stock work with your existing fuel system. The sending unit transfers from your factory tank to the new one, keeping your fuel gauge operational. The result is a vehicle that drives exactly as it did before, just with significantly more range on tap.

What to Look For

Not all long range tanks are equal, and a few things separate a quality unit from something that'll cause problems down the track.

Material is the starting point. The best underbody tanks are made from XLHDPE, cross-linked high-density polyethylene, a military-grade polymer that's seamless, impact-resistant, and built to handle temperature extremes. It's significantly tougher than the standard linear polyethylene used in most OEM fuel tanks, and it's the same material the US Department of Defence uses in combat vehicle fuel systems.

Fitment comes second. Vehicle-specific geometry is non-negotiable. A tank engineered to the exact dimensions of your platform will sit correctly, maintain factory ground clearance, and not interfere with mechanical systems. Universal or approximate-fit tanks create problems that aren't always obvious at install time.

Warranty comes third. A lifetime warranty on a fuel tank isn't just marketing. It's a signal of how much confidence a manufacturer has in their own product, and it's the minimum we'd expect from any tank we carry.

Brand We Stock

We currently carry Titan Fuel Tanks across the range. Founded in the USA in 2003, Titan built their reputation by addressing one problem: diesel truck owners who wanted to go further without planning every route around fuel stops. Their tanks are made from XLHDPE, manufactured in the USA, and backed by a lifetime warranty. As we expand this category we'll bring in further brands and fitments, but Titan gives us strong coverage across the American pickup platforms most commonly registered in Australia.

Installation

Long range replacement tanks are designed as a direct swap for your factory unit. Most owners with a reasonable level of mechanical confidence, access to jack stands, and a basic toolkit can complete the installation in a few hours. The process involves draining and dropping the factory tank, transferring the sending unit, and fitting the new tank with the supplied hardware. Instructions are included. If you're not comfortable working under a vehicle on a fuel system, a workshop installation is the sensible call.

One thing worth noting: once you're carrying significantly more fuel, your dash distance-to-empty readout may not accurately reflect the new capacity. Check the individual product page for your fitment for further detail on this.
