Which two components are included in a consumer vehicle fueling station to ensure safety and accurate dispensing?

• A. Metering system and breakaway device
• B. Breakaway device and flame arrestor
• C. Metering system and pressure gauge
• D. Nozzle retract mechanism and meter

Answer: (A)

Two components that ensure safe and accurate fueling are the metering system and the breakaway device. The metering system records exactly how much fuel is dispensed, which is essential for the customer’s transaction, proper inventory control, and safety oversight. It provides precise measurement of flow so the customer pays for what is actually delivered and the station can track usage and safety data. The breakaway device is a safety feature designed to prevent spills if a vehicle pulls away while the nozzle is still connected. When separation occurs, the device automatically seals off or shuts off the flow, dramatically reducing the risk of a fuel spill, fire, or environmental release. Together, these two parts cover both the accuracy of the dispense and the immediate safety response to a drive-off scenario. Other options don’t fit as the primary safety and accuracy pairing at consumer fueling stations. A flame arrestor helps prevent flame propagation in certain piping systems, but it isn’t part of the normal nozzle-to-vehicle dispensing mechanism. A pressure gauge shows pressure but doesn’t control flow or shut off automatically. A nozzle retract mechanism isn’t a standard safety feature for retail fueling and won’t provide the automatic shut-off function.
