Abstract:
1. A coaxial quill assembly comprising: an outer quill with a first dimension along a centerline; an inner quill positioned inside the outer quill and having a second dimension along the centerline; the outer quill and the inner quill being a matched pair such that the first dimension and the second dimension have a difference corresponding to a fuel system dimensional specification; the inner quill defining a first fuel passage; a second fuel passage defined by and between the inner quill and the outer quill; a retainer positioned in, but not obstructing, the second fuel passage in frictional contact with an interior surface of the outer quill and an exterior surface of the inner quill; and wherein the retainer permits relative movement of the outer quill relative to the inner quill along the centerline with an application of an adjustment force, but resists separation of the outer quill from the inner quill absent a forced disassembly.
