A fuel delivery system is provided for filling a fuel tank with a prescribed volume of fuel. The delivery system includes a fuel tank, a piezoelectrically-actuated fill control valve for controlling flow of fuel into the fuel tank, and a controller for controlling the closure rate of the fill control valve to accurately control the volume of fuel provided to the fuel tank. The controller receives an input corresponding to a measured volume of flow through the system and allows for closure of the fill valve at variable closure rates. The fill control valve is piezoelectrically-actuated and controlled by the controller such that each successive variable closure rate is relatively slower than the previous closure rate. In this way impact loads from shutting off the fill control valve are minimized to achieve a fill volume as close as possible to the prescribed volume.
