Diesel Storage Tanks

Diesel Storage Tanks

Fuel is one of the biggest line items on any property or worksite, and what you pay for it depends largely on how much you can take in one delivery. Our diesel storage tanks let you buy in bulk, hold it securely on site, and dispense it when you need it — without a trip to town and without paying retail at the servo.

Available in 5,000 and 10,000 litres, each offered tank only or with a 240V pump kit ready to dispense from day one.

What's included with every tank

Every tank arrives ready to work:

  • Poly-welded sealed lid — no removable cap, no perishable seal, no moisture path
  • 50mm anti-splash, anti-static fill line with non-return valve
  • 50mm low-level outlet with a lockable ball valve tap and camlock
  • Level gauge — read your fuel from the ground
  • Tank vent on a 300mm riser — set high so rain splashing off the lid can't get in
  • Water separator filter and suction fittings
  • Earth strap and rod for static discharge

Bulk diesel storage, made in Australia.

Why poly rather than steel?

Steel tanks rust from the inside. That rust becomes scale, scale becomes particulate, and particulate ends up in fuel systems where injector clearances are measured in microns — a repair bill that dwarfs whatever the tank cost.

Ours are rotationally moulded in one piece from diesel-grade, UV-stabilised polyethylene. Nothing to rust. No welds or seams to split. And a fraction of the weight of steel, which shows up in your freight bill and in how easily you can place it with the plant you already have.

Every tank is moulded in Australia at our Tamworth and backed by a 5 year warranty.

Sealed shut against water

Water is what ruins stored diesel. It's what lets microbial growth — diesel bug — take hold, and it's what turns a full tank into an expensive filter change and a workshop visit.

So we don't give it a way in. The lid on every RapidPlas diesel tank is poly welded shut. Not a screw cap, not a gasket, not a clamp ring — welded, as part of the tank. There's no lid to be left off after a fill, no seal to perish in the sun, and no join for condensation to work its way through.

A tank still has to breathe — air in as the fuel level drops, air out as it's filled — so there's one opening it genuinely needs. We've put it where the weather can't reach it: the vent sits on a 300mm riser, high enough that rain hitting the lid can't splash up and find its way in.

That thinking carries through the rest of the fit-out. A water separator filter comes fitted to every tank as standard, and tanks supplied with the pump kit carry a water captor filter at the point of dispense as well. Four defences against the same problem — two keeping water out, two catching what condensation leaves behind — and not one of them an optional extra.

Size the tank so a single bulk delivery fills it comfortably and you're not reordering more than about once a month. The 5,000L suits mixed farms, workshops and smaller contractors; the 10,000L suits broadacre, civil sites and transport depots running several machines hard. Both take the same pump kit, so it's a decision about capacity and footprint, not capability.

Stored properly, diesel stays stable for around 6 to 12 months. Water is what shortens it, because it lets microbial growth take hold, so keeping moisture out matters more than anything else. Our lids are poly welded shut rather than removable, so there's no cap to be left off and no seal to perish, and every tank includes a water separator filter as standard. Tanks supplied with the pump kit get a second filter as well — a water captor at the point of dispense. After that it's simply a matter of turning your stock over regularly.

Both sizes are available tank-only or with the PIUSI 240V pump kit — choose which on the product page. The pump kit is fitted during manufacture, so it's worth deciding up front. It runs on standard single-phase 240V power and delivers 70 litres a minute through a 6m hose with an automatic shut-off nozzle.

A level, smooth base that fully supports the tank and its contents, clear of rocks and sharp objects — a reinforced concrete pad or well-compacted crusher dust. Site it away from ignition sources, allow room for the delivery vehicle to reach the fill line, and connect the earth strap and rod before filling or dispensing.

No to both, and for different reasons. Petrol is a flammable liquid with different storage requirements, and these tanks aren't rated for it. AdBlue needs its own dedicated tank — it's a urea solution that corrodes copper and mild steel, it's ruined by even small traces of dust or fuel, and it degrades above 30°C. It can't share a tank with diesel, and it needs pump internals in stainless steel or specialised plastics rather than diesel-grade components.
