A tube assembly (22) for a gas turbine engine (10) includes a rigid tube (26) having first and second ends for connection to first port (120a) and second ports (24a) on the gas turbine engine (10). The first and second ports have different orientations providing for different installation vectors. The tube assembly (22) further includes a tube adapter (28) adjustably connected to the second port (24a) and a coupling (30), which, is, in turn, adjustably mounted to a distal end of the tube adapter (28) for connection with the second end of the tube (26).
