S&B 40 Gallon Long Range Fuel Tank | 2023-2026 Mercedes Sprinter AWD & Crew, Winnebago Revel AWD 2025-2026 & More

The shorter S&B 40 gallon tank for 2023+ Sprinters (2.0L diesel), including AWD vans, crew 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, fills the space between the OEM tank and transfer case plus about 5.2" rearward, and reuses your OE sending unit.

Fitment

• Mercedes Sprinter 2023–2026 (2.0L diesel), including AWD vans, 170" crew vans, and vans with plumbing 5"+ behind the OEM tank
• Winnebago Revel (AWD chassis): 2025–2026
• Jayco Terrain: 2024–2026
• Entegra Launch: 2024–2026
• Thor Sanctuary & Tranquility
• Will NOT fit 144" dually vans

Fuel gauge & range

• The fuel gauge reads accurately only on vans with the J51 fuel gauge option. Confirm with your VIN or installer. Vans without J51 can add the S&B Fuel Capacity Recalibration Module (TI1527-00), which also corrects distance-to-empty.
• 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.
