Abstract
A pump module includes a pump section that discharges evaporated fuel generated in a fuel tank to an intake path of an internal combustion engine. The pump module also stores correction information for correcting a rotation speed of the pump section based on a difference between a reference discharge characteristic of a reference pump section at a predetermined rotation speed and a discharge characteristic of the pump section at the predetermined rotation speed.
