Silent Hill: Homecoming
The gasoline tank, known here as the Gas Can, is an item found through the course of Silent Hill: Homecoming. In this game, its sole purpose is to hold enough gas to power the sump pump in the Shepherd family's basement. Alex Shepherd can find the gas can in the Shepherd family garage, in a locked box, which Alex must pry open with his steel pipe and take. Alex then siphons some fuel out of the tank of a crashed truck (some speculate that the truck belongs to Travis Grady) and return home and power up the sump pump, draining the flooded basement. This allows Alex access to the back of the Shepherd House.
