Fuel Pack (Promethium) is a Fuel Pack crafted at any Constructor. It has a fuel value of 30 (kWh). Fuel Pack (Promethium) may be used in any Fuel Tank as well as the Water Generator, Oxygen Generator, and H2/O2 Generator.

Once a survivor gains their bearings they may be able to use the Tech tree to access the H2/O2 Generator. This becomes a wise investment for Promethium fuel packs.
