A lubrication circulation system may comprise a first oil pump (134;164) configured to retrieve oil from a bearing compartment (138,140;168,170), and a second oil pump (132;162) located separately from the first oil pump (134;164) and configured to retrieve the oil from a fan-drive gear system compartment (136;166). The first oil pump (134;164) may be configured to provide the oil to the bearing compartment (138,140;168,170) and the fan-drive gear system compartment (136;166). |
