The dual fuel quill assembly may comprise a cylinder head including a main bore and a receiving cavity, an outer quill tube, an inner quill tube nested within the outer quill tube, an adapter slidingly received inside the main bore of the cylinder head, and a manifold secured to the adapter. The adapter may be moveable between a first position and a second position and may define an axial bore configured to receive the outer quill tube and the nested inner quill tube. The manifold may define a recess configured to compress the outer and inner quill tubes against the cylinder head cavity when the adapter is in the second position.
