Abstract
A fuel injector for a gas turbine engine includes an injector body having a feed arm with a nozzle body mounted thereto. A fuel conduit fluidly connects a fuel inlet portion of the feed arm to a fuel circuit in the nozzle body to form a fuel path through the injector body and an insulative gap is defined between the fuel conduit and an inside of the feed arm wall to thermally insulate the fuel path of the injector body. An aperture through the feed arm wall provides fluid communication between the insulative gap and ambient conditions existing on an outside of the feed arm wall.
