The Jerry Can is a liquid container which can hold up to 19 L of diesel fuel or water. It is a refillable container.
The Jerry Can, also referred to as Diesel Fuel, is mainly used to power Vehicles and Generators. It can be used by facing the machinery and entering the inventory [Default:G], then dragging the fuel into the corresponding slot. How much a single tank fills depends on the Vehicle.
Jerry Cans may also be used as impromptu Molotov Cocktails by placing the can near the desired target and shooting it. The can will explode in fiery inferno damaging everything in the vicinity.
Jerry Cans are very heavy, so lugging them around without reason is not recommended. They are quite a frequent sight at gas stations, auto repair shops, garages, and hardware stores. The amount of fuel found in a Jerry Can varies and they can be refilled from any of the gas pumps found in the game which have fuel.
Jerry Cans can be emptied of all fuel and be used for water storage. The large capacity of Jerry Can allow quick transfer of water from Water Collectors to Water Purifiers and finally to Water Barrels for final storage.
