This 200L underbody poly watertank carries 200 litres of fresh water under your ute or truck, which keeps the tray free for tools, crates or camping gear. The low 300mm centre height lets the tank sit up under the chassis, meaning ground clearance stays practical for bush tracks and work sites. Internal baffles slow water surge as you brake or corner, which keeps the vehicle more settled when fully loaded.

UV stabilised food grade polyethylene handles harsh Aussie sun, meaning the stored water stays suitable for general use trip after trip. Extra thick one-piece moulding cops vibration and dust without the weak points you get from multi-piece tanks. Threaded 32mm and 25mm ports at both ends give you options for fillers, drains and pump feeds, which makes this tank a smart buy for custom touring and work setups.

Q: Can this 200L underbody tank store drinking water?

A: Yes, the tank uses food grade polyethylene that meets Australian Standards for food and water contact. This means the material does not leach common plasticisers into the stored water under normal conditions. A proper cleaning routine before first use and between trips helps maintain water taste. Downstream filters or treatment can be added if your application requires.

Q: Do mounting brackets or straps come with the tank?

A: No, the tank is supplied on its own without brackets or straps. This lets installers build supports that match the specific chassis, tray and load path on each vehicle. A qualified fitter can select suitable steel or alloy mounts to spread the tank weight. Correct support under the base and sides helps prevent stress points and long-term distortion.

Q: What size fittings do I need for plumbing?

A: The tank includes 32mm and 25mm threaded inlets and outlets. These thread sizes suit common hose tails, valves and pumps used in 4x4 and commercial setups. Your installer can choose which ports to use for fill, breather and outlet lines. Unused ports can be blanked off with matching threaded plugs.

Q: Who should install this underbody tank?

A: The manufacturer recommends that only a qualified person installs the tank. A professional fitter can assess chassis layout, exhaust proximity and suspension travel before drilling or mounting. Correct installation considers clearance to moving parts and road debris. This approach helps the tank go the distance in real-world touring and work conditions.

Q: Can the tank be used above the tray instead of underbody?

A: The tank can sit wherever the dimensions and structure support its filled weight. Many users still prefer underbody mounting to keep the tray clear and lower the centre of gravity. If mounted on top, the support surface must spread the load across the full base. Secure tie-downs are also required to control movement under braking and cornering.
