The scavenge pump assembly (70) includes a drive shaft (72), a plurality of scavenge pumps (76), and a scavenge return manifold (78). Each of the plurality of scavenge pumps (76) includes a pump rotor (88) coupled with the drive shaft (72). The scavenge return manifold (78) includes a manifold body (90) forming a common outlet passage (92) and a plurality of inlet passages (94) of the scavenge return manifold (78). The common outlet passage (92) includes a manifold outlet (98) of the scavenge return manifold (78) connected in fluid communication with the oil tank (68). Each of the plurality of inlet passages (94) includes a manifold inlet (96) of the scavenge return manifold (78) connected in fluid communication with a respective one of the plurality of scavenge pumps (76). Each of the plurality of inlet passages (94) extends in an oblique direction from the manifold inlet (96) to the common outlet passage (92).
