摘要

The module has a reservoir arrangement (200) which is provided with a filter (280) that removes the foreign particle present in the diesel fuel. A fuel pump circulates the diesel fuel flowing through the filter, to the diesel engine. A pump connection return path (210) provided between the filter and fuel pump, supplies the diesel fuel by a supply line to the diesel engine, and returns the fuel to fuel pump without consumption by the diesel engine and without passing through the filter.
