ABSTRACT:
A fuel system for a gas turbine engine removes oxygen from fuel with a fuel stabilization unit (FSU). The FSU includes a first vacuum stage, where vacuum pressure is created by an ejector and a second vacuum stage where vacuum pressure is created by the ejector and a vacuum pump. The vacuum stream from the first vacuum stage and the second vacuum stage flow through the ejector. The vacuum stream from the second vacuum stage is all that passes through the vacuum pump.
