A gas turbine fuel injector includes a nozzle body having a radially inner wall proximate to an internal air path and a radially outer wall. An insulative gap is defined between the radially inner and outer walls. The inner and outer walls are adapted and configured for relative axial movement at a first interface. An inhibitor ring is disposed proximate a downstream end of the inner wall for discouraging fuel from entering the insulative gap. A second interface is formed between the downstream end of the inner wall and an upstream end of the inhibitor ring to accommodate relative axial movement of the inner and outer walls.

What is claimed is: 1.
