FUEL TANK REPAIRS

Keeping your fleet operational is critical — every hour of downtime costs you time, money, and productivity.

Our highly skilled technicians deliver end‑to‑end repair solutions for all types of fuel tanks.

From leak detection and structural repairs to fittings, mounts, and compliance checks, we restore your tanks to reliable, road‑ready condition. We work efficiently, with a strong focus on safety and quality, so your vehicles spend less time in the workshop and more time on the road.

FUEL TANK HYDRAULIC CONVERSIONS

We specialise in transforming standard tanks into efficient dual-purpose fuel and hydraulic tanks, giving your vehicle a powerful, integrated solution.

By converting your existing tank into a combined unit, we enable your vehicle to:

  • Safely store diesel and hydraulic oil in a single, well‑engineered system
  • Power auxiliary hydraulic equipment directly from the vehicle
  • Reduce the need for separate hydraulic reservoirs and extra mounting space
  • Simplify plumbing, reduce weight, and streamline maintenance

Each conversion is custom‑built to suit your vehicle and application, with careful attention to safety, capacity, heat management, and long-term reliability. The result is a clean, professional hydraulic power solution that maximises performance while keeping your setup neat, compact, and easy to service.
