Tempo brand standard rectangular fuel tank. Includes a 3/8" hose barb fitting on a coupler with 90degree elbow fitting to keep gas line tucked in within the width of tank. The "sight glass" small clear plastic piece is cracked and will need to be glue patched with J.B. Weld or other gasoline resistant epoxy or Super Glue! Otherwise tank is good and spotless clean inside. It was just used in a boat on Wednesday. Tank also has a built in 12volt electric sending unit to connect to an electric fuel gauge. Only $18 and you easily fix it!
