100 Gallon Diamond Plate L-Shape Aluminum Fuel Tank

Keep in mind the mounting tabs extend out 1.5 inches and the fill cap on the top of the tank adds 2.5 inches to the height.

The steel tank is built with 12 gauge aluminized steel and includes a black powder coat finish for long lasting outdoor durability.
