Auxiliary tank FAQs
Does a bigger tank always mean a better touring setup?
No. More fuel volume also means more mass when full. The best choice balances range goals, payload, fitment, clearance and how the vehicle is actually used.
Can I estimate range from litres alone?
Only as a rough planning exercise. Real consumption changes with terrain, speed, tyres, accessories, towing and load, so this page does not promise a specific range.
Should the tank be professionally installed?
Yes. Fuel-system work should be completed and checked by a suitably qualified installer, with applicable local rules and product instructions followed.
Need help checking tank compatibility?
Send your powertrain, model year and list of rear or underbody accessories before you order.
