A fuel supply system includes a covering member, a subtank, a first housing on the covering member to project toward the subtank, terminals in the first housing, a second housing fitted to the first housing, and lead wires in the second housing connected respectively to the terminals. The first housing includes a fitting recess opening toward the subtank, and a partition wall dividing the recess into spaces, each of which receives a corresponding terminal. The second housing includes a fitting projection fitted into the recess, a slit dividing the projection into blocks, each of which receives a corresponding terminal, the partition wall being inserted in the slit, and axial holes, each of which accommodates a corresponding wire. Each wire includes a corresponding one of elastic seal members. Each seal member seals a gap between a corresponding wire and a wall surface of a corresponding axial hole.
