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

The maximum length of an LP-gas transfer hose on an LP-gas vehicle fuel dispenser is specified as 18 feet in NFPA 58. This regulation is in place to ensure both safety and efficiency during the transfer of liquefied petroleum gas. A shorter hose length minimizes potential hazards associated with movement and accidental damage, while also maintaining a more manageable and efficient flow of gas during dispensing.

Hoses that are too long can create complications in handling, lead to increased risk of tangling or being inadvertently pulled, and might affect the delivery rate of gas. Thus, the 18-foot limitation strikes a balance between operational flexibility and safety concerns. When setting up or inspecting fuel dispensers, compliance with this standard is essential to ensure the equipment operates within designated safety parameters.
