Agile 20-Gal Auxiliary Sprinter Fuel Tank

There are no gas stations in the great outdoors!

Extended range fuel tanks not only prevent you from being stranded but allow you and your family to explore deeper into the wilderness than ever before. We worked exclusively with Aero Tanks to design and manufacture this auxiliary fuel tank for Mercedes-Benz Sprinter vans.

Yes, will our tanks allow you to go further between fill-ups, but that’s useless if they hamper the off-road capabilities of your rig. By mounting our auxiliary tanks as centrally as possible underneath your rig we keep the center of gravity low to ensure predictable handling on unpredictable terrain. Our tanks are internally baffled to prevent sloshing. Stainless steel construction (double-layered on the bottom) ensures a corrosion-free life & impact damage for years to come.

This is a transfer-style auxiliary tank. Fuel is pumped into this tank through a filler neck mounted in the rear fender. We offer a side-filler neck as an upgrade option. Stored fuel is pumped into the main tank via a switch-controlled electric fuel pump.

  • 20 Gallon Fuel Capacity
  • Tank is mounted underneath the driver side of the vehicle outside the frame rail (next to the factory fuel tank)
  • Filler neck located in rear passenger side wheel well
  • Side-filler neck upgrade option available
  • Includes high-volume fuel transfer pump

Priced at $1595 (+installation)
