47 Gallon Replacement Fuel Tank for 2019-2022 Mercedes Sprinter 144" and 170" Wheelbase

Maximize your Mercedes Sprinter's fuel capacity with the S&B Filters 47 Gallon Expansion Tank. This tank is designed for simple plug-and-play installation, making it easy to swap out your standard 24-gallon tank for a powerful 47-gallon upgrade. It mounts in the stock location and includes an additional rear strap for extra stability, efficiently utilizing the space both in front of and behind the original tank without extending further toward the driver’s side.

Your Fuel Gauge Works Like Normal
No need to worry about faulty fuel readings. S&B’s design keeps your fuel gauge accurate. While the gauge remains on "full" for the first 5-7 gallons, it will continue to drop and function normally after that. Keep in mind, however, that your vehicle will still calculate the distance to empty based on the stock fuel capacity. For instance, at 20 MPG with a full 47-gallon tank, your true range is 940 miles, though your vehicle will show 480 miles to empty.

Built to Last. Backed by a Lifetime Warranty
Constructed from robust ¼” thick crosslink polyethylene, this tank is engineered for durability. Whether you're venturing off-road or embarking on long trips, the S&B 47 Gallon Expansion Tank is tough enough for any challenge and comes with the peace of mind of a lifetime warranty.

Boost your Sprinter’s fuel capacity with confidence, knowing you'll have fewer stops and reliable performance for years to come.
