An attitude sensing arrangement for triggering a shutoff mechanism on a fuel dispensing nozzle 18 comprising a rolling element 86 placed inside a non-cylindrical chamber 84 that is sealed with a plug 88 such that the rolling element 86 may move freely inside the chamber 84. A vacuum sensing path 76 passes from a sensing port 74 in the nozzle spout 72, through a vacuum sensing tube 70, into the non-cylindrical chamber 84, and into a venturi-generated vacuum chamber 68. The attitude sensing arrangement is configured such that the rolling element 86 blocks a shutoff port 92 in the non-cylindrical chamber 84 when the nozzle 18 is raised past a certain shutoff angle. When the vacuum sensing path 76 is blocked by the rolling element 86 in this manner, the shutoff mechanism closes the main fuel valve 48.
