FAQs What is a self-bunded fuel tank?A self-bunded tank is a double-walled diesel tank with an integrated outer bund that contains leaks or overfill, reducing environmental risk and helping meet common compliance requirements. Are cube fuel tanks compliant for diesel?Yes—cube tanks are designed for diesel storage and refuelling. Choose certified models and pair them with appropriate pumps, filtration and overfill protection to suit your site rules. How big should my bunded diesel tank be?Start with your weekly consumption and delivery frequency. Our range caters to 11,000 to 110,000 self-bunded tanks to balance price, footprint and logistics. Can one tank store both Diesel and AdBlue (DEF)?No. Use Combo Diesel/AdBlue systems with segregated compartments and DEF-compatible components to avoid contamination. Do I need single-skin or self-bunded?Single-skin suits controlled areas with separate spill bunding. Self-bunded reduces spill risk and usually simplifies approvals and site works. What accessories should I add to a new tank?Common add-ons include high-flow diesel transfer pumps, 10 μm filtration with water separation, digital meters, automatic tank gauges / high-level alarms, diesel hose reels, and fuel management systems for user/vehicle tracking. Which standards apply in Australia?Site requirements vary, but diesel storage commonly references AS1940 guidance and related standards. Always confirm your local obligations before installation.
