ATTA 45 Gallon Diesel Auxiliary Below Bed Rail Tank AT45RBR
The ATTA 45 Gallon Diesel Auxiliary Tank (AT45RBR) is built for diesel truck owners who need added fuel capacity without giving up bed space
Designed to sit below the bed rails, this slim-profile tank works with both hard and soft tonneau covers and fits short or long bed Ford, Dodge, and GM trucks. With a width of just 12 inches, it’s ideal for daily drivers, haulers, and long-distance applications. The rear driver-side fill neck ensures simple access, even with the bed covered.
Pair it with either the Push’N’Fuel or Freedom Fill system (sold separately) for automatic or manual fuel transfer to your main tank
