A fuel supply device includes a subtank in a fuel tank, a fuel pump in the subtank having a first pump unit suctioning fuel in the subtank to supply fuel to an external equipment and a second pump unit suctioning fuel outside the subtank to pump fuel into the subtank, and a filter connected to a first suction port of the first unit and a second suction port of the second unit and filtering supply fuel supplied to the equipment and pump fuel pumped into the subtank. The filter includes a case, a first filter, and a second filter. The first filter in a first passage of the case directing fuel in the subtank into the first port filters the supply fuel. The second filter in a second passage of the case directing fuel outside the subtank into the second port filters the pump fuel.
