Abstract
A quill connector for a fuel system in an engine includes an elongate quill body defining a fuel conduit having a proximal accumulator segment, and a flow limiter subassembly, for limiting oversupplying of a pressurized fuel, positioned at least partially within the accumulator segment. The subassembly includes a seat component attached to the elongate quill body and supporting a guide component wherein a hydraulically actuated valve and a biaser are disposed. The valve is movable to a closed position during supplying pressurized fuel to a fuel injector, to interrupt a flow of the pressurized fuel thereto.
