<p>A pre-pay fuel system having a fuel nozzle (1) with automatic cutoff provisions (12, 18, 32) when a full tank exists or unwanted tank pressure conditions are detected is also provided with a low fuel pressure controlled cutoff (22, 44). The fuel pressure cutoff (22, 44) allows rapid response to permit fuel flow when high pressure exists in the nozzle (1) and provides a nozzle flow cutoff after a predetermined time delay when low fuel pressure exists in the nozzle (1).</p> |
