Chemical Flamethrower Regulator
The Regulator reduces fuel consumption so the Chemical Flamethrower can burn enemies for longer periods.
How it works
IGN describes the Regulator as reducing fuel consumption and allowing longer burns. It is in a locker opposite the nap pods in the Laboratory’s North Lab Area Nap Room. Fextralife says the Nap Room must first be powered using the Signal Modulator before the upgrade can be collected. The passages do not state exact fuel savings or burn duration.
