The present disclosure is directed to a sump housing for a gas turbine engine. The sump housing includes a base portion and a first wall extending outwardly from the base portion. The first wall and the base portion at least partially define an inner chamber. A second wall is positioned outwardly from the first wall and extends outwardly from the base portion. The base portion, the first wall, and the second wall at least partially define an outer chamber positioned outwardly from the inner chamber. A projection extending inwardly from the first wall engages a bearing assembly. The base portion, the first wall, the second wall, and the projection are integrally coupled together.
