A quill assembly includes a first quill tube and a second quill tube nested within the first quill tube. A first compression assembly includes a first piston operably coupled to the first quill tube and fluidly communicates with the first fuel rail to apply a first piston axial force against the first quill tube inlet end, and a first spring operably coupled to the first piston and configured to apply a first spring axial force against the first quill tube inlet end. A second compression assembly includes a second piston operably coupled to the second quill tube inlet end and fluidly communicates with the second fuel rail to apply a second piston axial force against the second quill tube inlet end, and a second spring operably coupled to the second piston and configured to apply a second spring axial force against the second quill tube inlet end. |
