Applications
What Is a Fuel Trailer Used For?
Fuel trailers solve a fundamental operational problem — getting diesel and other fuels to the equipment that needs it, wherever that equipment is working. Rather than bringing machinery to a central fuel point and losing productive hours, a fuel trailer brings the fuel to the machine. In Australia's remote and regional operating environments, this is often not optional — it is the only practical way to keep operations running.
Agriculture & Farming
Refuelling tractors, harvesters, headers and irrigation pumps across large properties — eliminating trips to fixed tanks during peak planting and harvest periods.
Construction & Civil Works
Mobile refuelling for excavators, graders, rollers and site vehicles across active construction sites where the fuel point needs to follow the work.
Mining Operations
On-site diesel delivery to heavy plant, light vehicles and auxiliary equipment at remote mine sites where commercial fuel access is not available.
Transport & Fleet
Emergency fuel delivery and breakdown refuelling for truck fleets — keeping vehicles moving without waiting for roadside assistance or travelling to a service station.
Remote & Off-Grid Sites
Infrastructure and utilities projects in remote locations where the nearest service station may be hours away — fuel trailers provide reliable on-site supply.
Event & Temporary Sites
Generator refuelling and temporary power supply at events, disaster recovery operations and construction camps where permanent fuel infrastructure is not available.
Buying Guide
How to Choose the Right Fuel Trailer
Selecting the right fuel trailer for your operation requires matching the trailer's capacity, tank construction, pump type and compliance configuration to your specific application. Working through these six factors before purchasing ensures your trailer is fit-for-purpose and compliant from day one.
01
Fuel Capacity
Choose a capacity that covers your daily refuelling requirements without excessive trips back to base. Factor in the number of machines being refuelled, their average fuel consumption per shift and the distance from your resupply point. Undersizing creates downtime; oversizing increases tare weight and towing requirements unnecessarily.
02
Fuel Type
Confirm compatibility with your fuel — diesel, petrol, AdBlue or a combination. Multi-compartment trailers allow dual-fluid carry in a single unit. Note that petrol triggers stricter ADG thresholds than diesel — confirm your fuel type before specifying compliance requirements.
03
Self-Bunded or Single-Wall Tank
Self-bunded trailers have double-wall construction that captures 110% of tank volume in a spill — meeting AS1940 bunding requirements without external infrastructure. Single-wall tanks may require additional bunding at the dispensing location. For most Australian operations, self-bunded is the recommended and most compliance-straightforward choice.
04
Pump Type
Match the pump to your power source — 12V DC for ute-powered mobile use; 24V DC for heavy vehicle-powered applications; 240V AC where mains power is available; air-operated for hazardous area environments or sites with compressed air. Flow rate requirements also determine pump selection — high-volume plant refuelling needs a higher flow rate than light vehicle top-ups.
05
Terrain & Mobility Requirements
Highway-rated trailers are suited to on-road towing between sites. Off-road rated trailers with higher clearance, robust axles and appropriate tyre ratings are needed for active construction, mining or agricultural terrain. Confirm tow vehicle GVM and GCM compatibility before selecting trailer size.
06
ADG Code Compliance
If transporting over 450L of Class 3 flammable liquid (petrol) or regulated quantities of diesel on public roads, the trailer must comply with the Australian Dangerous Goods Code — including placarding, tank certification to AS 2809, driver licensing and mandatory safety equipment. Confirm your volume and fuel type to determine what ADG requirements apply before purchasing.
Key Features
What to Look For in a Professional Fuel Trailer
A professional fuel trailer is more than a tank on wheels. These are the features that separate a fit-for-purpose unit from a basic fuel carrier — each contributing to safety, compliance, fuel quality and operational efficiency.
Self-Bunded Double-Wall Tank
110% secondary containment — AS1940 compliant spill protection without additional bunding infrastructure at the dispensing site.
Digital Flow Meter
Accurate litre counting with resettable batch counter and cumulative totaliser — essential for cost allocation and compliance records per vehicle or machine refuelled.
Fuel-Grade Hose & Auto Nozzle
Diesel-rated hose and automatic shut-off nozzle — prevents overfill and reduces the spill risk during dispensing to vehicles and equipment.
Fuel Filtration
In-line filter and water separator protecting modern common rail diesel engines from particulates and water ingress during mobile refuelling operations.
Lockable Pump Bay
Protects pump, meter and hose from weather, dust and theft when the trailer is unattended on remote sites or stored between operations.
ADR-Compliant Trailer Chassis
Road-registered with compliant lighting, reflectors and braking — required for legal on-road towing and registration in all Australian states and territories.
Compliance
Legal Requirements for Fuel Trailers in Australia
Transporting and operating fuel trailers in Australia is regulated at both the federal and state level. Understanding which requirements apply to your trailer, fuel type and volume before you purchase protects you from non-compliance penalties and operational disruption.

Frequently Asked Questions
Fuel Trailer FAQ
What is the difference between a self-bunded and a single-wall fuel trailer?
A self-bunded fuel trailer has a double-walled tank — the inner tank sits inside an integral outer bund that captures 110% of tank volume in a spill. This meets AS1940 bunding requirements without needing external containment infrastructure at the dispensing location. A single-wall trailer has one tank wall and no integral containment — it may require a bunded drip tray or compound at the dispensing site to meet regulations. For most Australian operations, self-bunded is the simpler, safer and more compliance-straightforward choice.
Do I need a Dangerous Goods licence to tow a fuel trailer in Australia?
It depends on the fuel type and volume. Petrol is a Class 3 flammable liquid — transporting more than 450L on public roads requires ADG Code compliance including appropriate licensing, signage and vehicle specification. Diesel is combustible rather than flammable and attracts different thresholds. State regulations also vary. A-FLO recommends confirming your specific volume, fuel type and route with the relevant state transport authority or calling 1300 235 623 for guidance before purchase.
What pump do I need on a fuel trailer for mobile farm use?
For typical farm fuel trailer applications — refuelling tractors, harvesters and machinery in paddocks — a 12V DC pump powered from the tow vehicle is the most practical option. It requires no external power source, starts with the vehicle's ignition circuit and delivers adequate flow rates for agricultural refuelling. For higher-volume applications or where a 24V truck is the tow vehicle, a 24V DC pump is the appropriate choice. A-FLO can advise on the right pump and flow rate for your specific machines and daily fuel volume.
Can a fuel trailer carry both diesel and AdBlue?
Yes — multi-compartment fuel trailers are available with separate tanks and dedicated dispensing systems for diesel and AdBlue in a single unit. AdBlue requires stainless steel wetted components and a completely separate, dedicated dispensing system to prevent cross-contamination — even trace diesel contamination can degrade AdBlue and damage SCR systems. A-FLO can specify the correct multi-compartment configuration for dual diesel and AdBlue carry.
Does A-FLO supply fuel trailers with flow meters and fuel management systems?
Yes. A-FLO fuel trailers are available with digital flow meters as standard — providing accurate litre records for every refuelling event. For operations requiring driver or vehicle identification, access control and digital reporting, A-FLO's FLUIDTRACK and PIUSI Bsmart fuel management systems can be integrated into a trailer-based dispensing setup — enabling per-vehicle fuel tracking and compliance records even in a mobile refuelling context. Call 1300 235 623 to discuss your requirements.
