Restarting a diesel engine e.g. your tractor after it had emptied the tank was very difficult back in the day. There wasn't an electric fuel pump to pump it from the tank. It had to be sucked by the mechanical, engine driven, diesel injector pump. Rather difficult if the engine has no fuel to get going. Once you did get the engine running with out cutting out again you'd know it was finally sucking diesel
Now we're sucking diesel
