The ATI 60 Gallon Auxiliary Diesel Fuel Tank (Wedge Style) is designed to provide extended diesel fuel capacity while maintaining improved rear visibility and cab clearance. The wedge-shaped profile lowers the tank height toward the cab, making it ideal for drivers who want additional range without obstructing rear windows or interfering with bed-mounted accessories. This auxiliary tank connects to the factory fuel system using a Gravity Feed Installation Kit (sold separately), allowing diesel fuel to transfer naturally into the primary tank without the use of pumps or electrical components. Constructed from premium aluminum, the tank is DOT approved for highway and commercial use , meeting and exceeding Title 49 CFR 393.65 requirements. Purpose-built for auxiliary diesel fuel applications , ATI delivers durable, American-made performance trusted by work trucks and fleet operators.
