摘要： A fuel supply device includes a relief valve, a pressure regulator, and a controller. The controller controls a first pump to send fuel into an engine through a first passage, and controls a second pump to send fuel into a second passage to communicate with the first passage. The relief valve discharges fuel from the second passage when a fuel pressure of the second passage is higher than a relief pressure. The pressure regulator discharges fuel when a fuel pressure of fuel chamber is higher than a regulation pressure higher than the relief pressure in a state that a fuel pressure of backpressure chamber is equal to the relief pressure.
