Full text
8.148. The pumps of a motor fuel dispenser installed or altered in a motor fuel dispensing outlet must have a mechanism that will prevent the dispenser pump from operating until a dispensing nozzle has been removed from its housing if the pump has been hand-activated, and that will shut off the pump when all nozzles have been reinserted in their housing; if the pump is connected to a satellite dispenser, it must also have a mechanism that prevents simultaneous dispensing of motor fuel.
The first paragraph does not apply to a dispenser that has a coiling mechanism.
