Do you have an Auxiliary Fuel Tank? Read why using these with our tanks will void the Lifetime Warranty.

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.

Important: The fuel gauge will only work accurately on vans with the J51 fuel gauge (optimized for aux. fuel tap). All 2020+ Revels should have been built with this option but please confirm by sending us your vin or consulting with your installer.
