⚠️ Important Notice for Vans Using Auxiliary Fuel Tanks

S&B tanks and OEM tanks include rollover valves that must maintain vapor space for safe operation.

Do NOT use:

• Gravity-feed transfer tanks

• Electronic transfer tanks that allow overfilling

Overfilling can:

• Force rollover valves closed

• Pressurize the tank

• Cause leaks or tank failure

• Void the S&B warranty

If you're unsure about your aux system, ask before installing.

Fuel Gauge Accuracy Note

For vans without the Mercedes J51 fuel gauge option, your gauge may read incorrectly with a high-capacity tank.

If your van does not have J51, you will need:

• S&B Module TI1349-00

Contact your Mercedes dealer to confirm if your van is equipped with J51.
