A labyrinth box can include a housing that has an open end, a closed end, and defines two cavities. A cover is configured to cover the opening and can include a divider that extends into one of the two cavities of the housing to define first and second chamber passageways in that cavity. An inlet port is located in the bottom closed end of one of the cavities and an outlet port is located in the other of the cavities. The surfaces that define the chambers can be configured such that the box can be oriented in different positions and still work, namely, in horizontal and vertical positions. When in the vertical position, the divider can include surfaces that are angled off of the horizontal plane and towards the inlet port such that water and debris will return to the inlet port via gravity. The labyrinth box can be used in applications that require separation between fluids and/or debris, such as in a fuel tank pressure sensor system in which rainwater, backsplash, or other debris, should be kept clear from a pressure sensor that has a portion exposed to atmospheric pressure for sensor reference purposes.
