Product Description
ATI TTL85S is a DOT special-permit, 85-gallon, split L-shaped aluminum refueling tank that carries two separate 42-gallon compartments (42/42). It nests under a crossover/chest toolbox so you can haul fuel and keep bed storage. Built from .125" diamond-plate aluminum, it’s fully baffled, pressure/leak-tested, and ready for legal refueling when installed and used per ATI guidance.
