Identical models with the same fuel capacity can use different OEM tank layouts (single vs. twin / different shape), so the underbody photo lets us confirm the exact tank type for your vehicle.

How the long range system works

The auxiliary tank feeds your main tank on demand through a jet-pump you switch from the cabin, so you keep driving on the factory gauge while total range climbs.

Every kit includes

54L (14 Gallon) aluminum-magnesium alloy auxiliary fuel tank - your OEM tank stays in place

Fuel pump

Installation manual

Transfer is switched from the cabin, so your factory gauge keeps reading the main tank as normal. Manufacturer warranty against defects and weld failure; professional installation required.
