1. A method of assembling a gas turbine engine assembly comprising an engine core extending around a central axis, the method comprising:

  • coupling a gearbox to the engine core and arranging the engine core aft of the gearbox along the central axis, the gearbox including a lubrication system having a pump adapted to pressurize oil, a first sump located within a housing and configured to collect oil moved into the first sump by way of gravitational force when the housing is arranged in a first orientation, a second sump located within the housing and configured to collect oil moved into the second sump by way of gravitational force when the housing is arranged in a second orientation, and a manifold fluidly having a plenum;

    coupling the pump to a plenum of the manifold by a pump line;

    coupling the first sump to the plenum by a first-sump line;

    coupling the second sump to the plenum by a second-sump line; and

    blocking fluid communication into the plenum from one of the first sump or the second sump by coupling a configuration plate to the plenum.
