What is the maximum allowable length for the transfer hose on an LP-gas vehicle fuel dispenser?

The correct maximum allowable length for the transfer hose on an LP-gas vehicle fuel dispenser is 18 feet. This limitation is put in place to ensure safety during the dispensing process. A hose that exceeds this length could increase the risk of operational hazards, like kinks or damage, which can lead to leaks or spills. Additionally, having a standardized maximum hose length allows for safer maneuverability around the vehicle being fueled and reduces the likelihood of creating trip hazards in the dispensing area.

By keeping the hose to a maximum of 18 feet, dispensers can operate efficiently while adhering to safety regulations that help prevent accidents and ensure a safe refueling environment for both the operators and users. When hoses are excessively long, there are additional challenges in maintaining pressure and flow rates, which can also affect the overall efficiency of the fueling process.
