Overview & Setup Guide

Tank Types

  • Replacement: Swaps factory tank for higher capacity
  • Auxiliary: Adds a second tank with a transfer system
  • Underbody Protection: Skid-plate style guarding for rough tracks

Capacity Planning

  • Choose capacity for your typical legs (remote, towing, headwinds)
  • Balance added fuel weight vs payload and GVM
  • We’ll recommend a safe, practical size for your rig

Range & Economy

Real-world range depends on load, tyres, gearing, terrain and speed. A bigger tank gives flexibility to choose cheaper fuel and avoid risky detours.

Install & Integration

  • Neat plumbing with quality hose & fittings
  • Breather routing to reduce splash-back
  • Fuel gauge & sender integration as applicable
  • Road test and leak check

Clearance & Protection

We check exhaust, driveline and departure angles, and add guarding where it makes sense for your tracks and tyre size.

What We Need to Quote

  • Vehicle model/year & engine
  • Tyre size, tow weight & accessories
  • Typical trip distances & fuel stops

FAQs

Replacement vs auxiliary — which should I choose?

Replacement tanks keep things simple with one large tank. Auxiliary systems add a second tank and a transfer setup. We’ll recommend based on capacity target, space and budget.

Will departure angle or clearance change?

We check clearances during quoting and can add protection where required. For most touring heights and tyre sizes, changes are minimal.

Does a bigger tank affect payload?

Additional fuel adds weight. We’ll run the numbers with you and suggest a capacity that suits your payload and any GVM considerations.

How is the fuel gauge handled?

Integration depends on the vehicle and tank type. We’ll set up sender/transfer systems so the gauge and filling process are simple to use.

What info do you need to quote?

Vehicle details (engine, year), driving range goals, tyre size, towing and typical routes. Photos of your underbody setup help.
