1. A gas turbine engine comprising: a first shaft that interconnects a fan, a low pressure compressor, and a low pressure turbine;a second shaft that interconnects a high pressure compressor and a high pressure turbine, the second shaft configured to rotate at a faster speed than the first shaft;a geared architecture that interconnects the first shaft to drive the fan, the geared architecture comprising a gear assembly enclosed within a gear housing;a manifold assembly comprising a mounting plate having a mount interface attached to the gear housing and a flow plate attached to the mounting plate to provide a plurality of flow passages between the mounting plate and flow plate, the manifold assembly including at least one fluid inlet configured to receive fluid from a supply and at least one fluid outlet to direct the fluid into the gear housing;wherein the flow plate comprises a ring-shaped structure with a center opening defining a center axis and a first ring portion defined by a first inner peripheral surface extending circumferentially about the axis and a first outer peripheral surface spaced radially outwardly relative to the first inner peripheral surface;wherein the mounting plate comprises a ring-shaped structure with a center opening concentric with the center axis and a second ring portion defined by a second inner peripheral surface extending circumferentially about the axis and a second outer peripheral surface spaced radially outwardly relative to the second inner peripheral surface; andwherein the plurality of flow passages comprises at least a first flow passage formed adjacent to the first and second inner peripheral surfaces and a second flow passage formed adjacent to the first and second outer peripheral surfaces, the first and second flow passages extending circumferentially around the first and second ring portions to at least partially surround the central axis. 2. The gas turbine engine according to claim 1 wherein the mounting plate includes a first plurality of ports associated with the first flow passage and a second plurality of ports associated with the second flow passage, and wherein each port comprises a raised boss portion having an outer surface that is sealed against an inner flow passage surface of the flow plate, and wherein at least one port includes a port inlet that faces the flow plate and a port outlet that faces the gear housing. 3. The gas turbine engine according to claim 2 wherein the first flow passage includes a first radially innermost surface and a first radially outermost surface and the second flow passage includes a second radially innermost surface and a second radially outermost surface, and including a first seal engaging the first radially innermost surface, a second seal engaging the first radially outermost surface, a third seal engaging the second radially innermost surface, and a fourth seal engaging the second radially outermost surface. 4. The gas turbine engine according to claim 3 wherein the first, second, third, and fourth seals comprise o-rings. 5. The gas turbine engine according to claim 1 wherein the mounting plate includes one or more flange portions formed about an outer periphery of the mounting plate to provide the mount interface. 6. The gas turbine engine according to claim 1 wherein the mounting plate and flow plate are separate pieces that are secured together to form the flow passages. 7. The gas turbine engine according to claim 6 wherein the mounting plate and the flow plate each include openings configured to receive fasteners to attach the mounting plate and flow plate together. 8. The gas turbine engine according to claim 1 wherein the first and second flow passages are not fluidly connected to each other. 9. The gas turbine engine according to claim 8 wherein the at least one fluid inlet comprises a first fluid inlet to the first low passage and a second fluid inlet to the second flow passage, the first and second fluid inlets being separate from each other. 10. The gas turbine engine according to claim 8 wherein the second flow passage extends circumferentially about the first flow passage such that the second flow passage substantially surrounds the first flow passage.
