Important: The fuel gauge will only work accurately on vans with the J51 fuel gauge (optimized for aux. fuel tap). Please call your Mercedes dealer to confirm if you have this option. If you don’t have it, you will need TI1349-00 or TI1527-00. We recommend TI1527-00 as it also reprograms your Miles to Empty reading.
When using the auxiliary fuel tap on stock tanks, tap stops pulling fuel around 1/4 tank. With the S&B Tank, it will stop pulling fuel around 1/3-1/2 tank.
The S&B Tank comes with all the components to remove your 24 gallon tank and replace it with S&B's 45 gallon tank. The tank mounts in the stock location with an additional rear strap. The tank occupies the space forward and rearward of the original tank and does not stick out anymore toward the driver side than the original tank.
Even with more fuel on board, your fuel gauge will remain accurate thanks to S&B’s tank design. The gauge will stay on full for the first 5-7 gallons, but then continue to move as normal. The distance to empty however will still be calculated based on the stock fuel capacity. For example, @ 20mpg and a full tank (45 gallons) you will have 940 miles to empty but your vehicle will show you have 480 miles to empty.

Made out of ¼” thick crosslink polyethylene, these tanks are built to last and are backed by our lifetime warranty.
