The fuel delivery assembly of claim 1, wherein the securing member is rotatable with respect to the quill tube when the quill tube is disposed in the securing member after engaging in the interference fit. 3. The fuel delivery assembly of claim 1, wherein: the quill tube is movable in an axial direction with respect to the securing member when the quill tube is disposed in the securing member after engaging in the interference fit; andthe securing member projection and the quill tube projection are configured to limit axial movement of the quill tube with respect to the securing member when the quill tube is disposed in the securing member opening. 4. The fuel delivery assembly of claim 1, wherein the securing member includes an outer surface configured to attach to a surface in a cylinder head of an engine. 5. The fuel delivery assembly of claim 4, wherein the outer surface of the securing member further includes a surface configured to be gripped by a tool and located proximal to the surface configured to attach to the cylinder head. 6. The fuel delivery assembly of claim 1, wherein: the securing member projection includes a surface generally located a first distance from a longitudinal axis of the securing member;the quill tube projection includes a surface generally located a second distance from a longitudinal axis of the quill tube;the first distance is less than the second distance such that the securing member projection and the quill tube projection are configured to engage in the interference fit. 7. The fuel delivery assembly of claim 1, wherein at least one of the securing member projection or the quill tube projection is configured to provide greater resistance to removing the quill tube from the securing member than to inserting the quill tube into the securing member. 8. The fuel delivery assembly of claim 7, wherein at least one of the securing member projection or the quill tube projection includes a first edge and a second edge, the first edge being formed with a smaller angle than the second edge such that the at least one securing member projection or quill tube projection is configured to provide greater resistance to removing the quill tube from the securing member than to inserting the quill tube into the securing member. 9. The fuel delivery assembly of claim 8, wherein the first edge is formed with an angle within a range of 15 degrees to 20 degrees, and the second edge is formed with an angle within a range of 45 degrees to 60 degrees. 10.
