We build aluminium, stainless steel and steel fuel tanks for long-range, replacement, auxiliary and dual‑purpose diesel and hydraulic oil applications – engineered specifically for tough Australian conditions and demanding commercial use.
Custom Fuel Tanks for Trucks Australian Made by Highgate Engineers
Custom Fuel Tanks Built for Australian Conditions
Designed for Trucks and Heavy Vehicles
Our custom fuel tanks are built for:
- Prime movers and linehaul trucks
- Rigid trucks and tippers
- Heavy haulage and road trains
- Construction and civil trucks
- Mining and industrial vehicles
Every tank is made to suit the vehicle, mounting points and operating environment, helping maximise durability, range and uptime.
Aluminium, Stainless Steel and Steel Options
Highgate Engineers fabricates fuel tanks in:
- Aluminium – lightweight and corrosion‑resistant, ideal for long‑distance trucks where weight saving matters.
- Stainless steel – maximum corrosion resistance and durability, well suited to harsh, coastal or chemical environments.
- Steel – robust and cost‑effective for many truck and heavy vehicle applications.
We’ll recommend the most suitable material based on your vehicle, application and budget.
Types of Custom Fuel Tanks We Manufacture
Long Range Fuel Tanks
For operators who need extended range between fills, we manufacture long-range fuel tanks tailored to your truck and route:
- Increased capacity for linehaul and interstate transport
- Ideal for remote area operations, mining and regional freight
- Designed to integrate with existing mounts and plumbing
Our long-range tanks help reduce downtime, improve route flexibility and minimise refuelling stops.
Replacement and Upgrade Fuel Tanks
We provide replacement and upgrade tanks for trucks where the original tank is damaged, corroded, undersized or no longer available:
- Direct replacement tanks made to suit existing brackets and fittings
- Capacity upgrades while maintaining safe weight distribution
- Improved materials and construction for longer service life
Where possible, we can work off supplied measurements, drawings or samples to ensure a reliable fit.
Auxiliary and Transfer Fuel Tanks
Highgate Engineers fabricates auxiliary and transfer fuel tanks for heavy vehicles that require additional onboard fuel storage:
- Auxiliary tanks working in conjunction with the main tank
- Transfer tanks to support equipment or auxiliary engines
- Custom shapes to clear chassis components and bodywork
All systems are designed with safe operation, reliability and ease of maintenance in mind.
Dual‑Purpose Diesel and Hydraulic Oil Tanks
We also design and manufacture dual‑purpose tanks that combine diesel and hydraulic oil storage in a single, compact unit:
- Integrated designs with separate diesel and hydraulic oil compartments
- Efficient use of chassis space on trucks and heavy equipment
- Ideal for tippers, hook‑lifts, concrete pumps and specialised bodies
Each dual‑purpose tank is designed with appropriate baffling, port locations, venting and mounting arrangements to suit your hydraulic system and vehicle layout.
