Buyer Guide: Choosing the Right Bulk Diesel Tank

Specifying the wrong diesel tank for your site creates ongoing compliance, operational, and cost problems. Here's what to consider before purchasing:

Self-bunded vs single-skin — self-bunded tanks have an integrated outer bund providing 110% secondary containment. They're the default choice for most Australian sites because they simplify EPA and council approvals and reduce site works. Single-skin tanks require a separate engineered bund and suit sites where compliant bunding infrastructure already exists.
Capacity sizing — base your tank size on weekly fuel consumption and your supplier's delivery frequency. Oversizing ties up capital; undersizing means frequent deliveries and potential operational downtime. A-FLO's range covers 11,000L to 110,000L in self-bunded configurations.
Steel vs poly construction — steel self-bunded tanks suit high-volume permanent installations and heavy industrial sites. Poly tanks are better suited to lower-volume mobile, agricultural, and temporary applications where weight and relocatability matter.
Pump voltage selection — 12V pumps suit mobile and remote sites without mains power. 24V suits larger mobile plant. 240V delivers higher flow rates for high-throughput fleet refuelling where mains power is available.
Filtration requirements — 10-micron filtration with water separation protects modern common-rail diesel engines from fuel contamination. This is especially important for remote sites where fuel quality and storage conditions are harder to control.
Fuel management — for fleet operations, specify a fuel management system from the outset. User and vehicle tracking, digital metering, and reporting integration become significantly more expensive to retrofit than to include at installation.
Diesel/AdBlue requirements — if your fleet uses AdBlue (DEF), specify a Fueltainer Combo unit with segregated compartments and DEF-compatible hardware. Never store AdBlue in standard diesel hardware — contamination causes costly injector damage.
AS 1940 and local compliance — diesel storage commonly references AS 1940 and related standards. State EPA requirements and local council rules vary — always confirm your specific obligations before specifying tank size, bunding, and installation location.

Frequently Asked Questions — Bulk Diesel Tanks

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 — providing at least 110% secondary containment. This reduces environmental risk and simplifies compliance with AS 1940 and related Australian standards, without requiring a separate civil bund.

Are cube fuel tanks compliant for diesel storage in Australia?

Yes — Fuelcube and Fuelbox tanks are designed for diesel storage and refuelling. Specify certified models and pair them with appropriate pumps, filtration, and overfill protection to meet your site's regulatory requirements and local council obligations.

How big should my bunded diesel tank be?

Start with your weekly fuel consumption and your supplier's delivery frequency. A-FLO's self-bunded range covers 11,000L to 110,000L. The bund must be sized to contain at least 110% of the primary tank's capacity. Contact our team for a sizing consultation based on your specific operation.

Can one tank store both diesel and AdBlue?

No — diesel and AdBlue must never share the same tank or hardware. A-FLO's Combo Diesel/AdBlue Fueltainer systems provide segregated compartments with DEF-compatible components specifically to prevent contamination.

Do I need a single-skin or self-bunded diesel tank?

Single-skin tanks suit controlled areas where a separate, compliant engineered bund is already in place. For most Australian operations — farms, transport yards, remote sites, construction — a self-bunded tank is the simpler, lower-risk choice that typically streamlines EPA and council approvals.

What accessories should I add to a new bulk diesel tank?

Common additions include diesel transfer pumps (12V, 24V or 240V), 10-micron filtration with water separation, digital fuel flow meters, automatic tank gauges, high-level alarms, diesel hose reels, and fuel management systems for user and vehicle tracking. A-FLO can configure a complete system from the one supplier.

Which Australian standards apply to diesel tank installations?

Diesel storage commonly references AS 1940 (storage and handling of flammable and combustible liquids) and AS 1692 (steel tanks for flammable and combustible liquids). State EPA requirements and local council rules also apply and vary by location — always confirm your specific obligations before installation.

Do you supply bulk diesel tanks across all of Australia?

Yes. A-FLO supplies and installs bulk diesel tank systems nationally across VIC, NSW, QLD, WA, SA, TAS, NT, and ACT — including remote mine sites, regional agricultural operations, and metropolitan fleet depots.
