A fuel nozzle retainer kit includes a first retainer that is attachable to a fuel tank that has a skirt thereon. The first retainer extends over a fill port on the fuel tank. Additionally, the first retainer has elastomeric properties to engage and thus retain a fuel nozzle in the fuel port. A second retainer is attachable to a fuel tank that does not have a skirt thereon. The second retainer has a first portion that is mountable around a fill port of the fuel tank that does not have a skirt. The second retainer has a second portion which is pivotally coupled to the first portion. Additionally, the second portion is positionable to engage a fuel nozzle inserted into the fill port to retain the fuel nozzle in the fill port.

A robotic refuelling system and method for automatically operating a fuel station for refuelling vehicles includes a first detection unit for identifying the vehicle, a collaborative robot arm, and an adapter tool connected to the collaborative robot arm. The system is configured for detecting and identifying the vehicle, and controlling the collaborative robot arm and the adapter tool to engage at least one fuel dispenser unit of the fuel station and refuel the vehicle.

A collaborative robot arm for being used in an explosive environment includes electronics contained in at least one housing with at least one opening and a pressurization system configured for pressurizing the at least one housing with a gas at a predefined pressure level above atmospheric pressure.
