The Fuel Reservoir is a treasure found in Pikmin 2. It is located in the seventh sublevel of the Cavern of Chaos. The Fuel Reservoir may be near some airborne Blowhogs and some Cloaking Burrow-nits. Take them out along with the poison pipes so they won't harm your Pikmin as they carry it back to the ship's pod. It is actually a 9-volt Duracell battery.
