lets go back to the original question : Fuel pumps ON or OFF during refueling ?
whatever , both can be done , it is just "better" , more safe to do it with the pumps OFF.
on the technical side
now , to make your life more easy and not forget to put them back ON before engine starts , you can leave them ON , even if the engines do not need the pumps to start and run ... because they are LOW pressure pumps , the HIGH pressure pumps are fitted on the engine gearboxes , whatever the engine family/type is ...
