S&B 40 Gallon Long Range Fuel Tank | 2019-2022 Mercedes Sprinter Crew & Dually, Winnebago Revel 2019-2024 & More

The shorter S&B 40 gallon tank for 2019–2022 Sprinters and Sprinter-based RVs where the 45 gallon tank won't fit. That includes crew vans, dually vans, and builds with plumbing or equipment behind the factory tank. It's a plug-and-play replacement for the factory 24 gallon tank that mounts in the stock location with the included straps, extends about 11.2" forward and 5.2" rearward of the original tank, and reuses your OE sending unit.

Fitment

• Mercedes Sprinter 2019–2022 (3.0L diesel), including 144" and 170" crew vans, 144" dually vans, and vans with plumbing 5"+ behind the OEM tank
• Winnebago Revel: 2019–2024 (4WD chassis), including 2020+ Revels with AGM or lithium batteries
• Thor Sanctuary & Tranquility: 2024
• Jayco Terrain: 2022–2023
• Entegra Launch: 2022–2023
• Grech Turismo: 2020–2024
• Airstream Interstate 24X / 24GT: fits with slight adjustment

Fuel gauge & range

• The fuel gauge reads accurately only on vans with the J51 fuel gauge option. All 2020+ Revels should have it, but confirm with your VIN. Vans without J51 can add the S&B Fuel Capacity Recalibration Module (TI1527-00).
• The gauge stays on full for the first 5–7 gallons, then moves normally.
• Without the recalibration module, distance-to-empty still calculates from the stock 24 gallon capacity.
• The auxiliary fuel tap stops drawing at about 1/3–1/2 tank (vs. 1/4 tank on stock).
• Using an auxiliary transfer/gravity-feed fuel tank with an S&B tank voids the lifetime warranty.
