Abstract
Provided is a fuel pump module for supplying diesel fuel. The fuel pump module in accordance with exemplary embodiments of the present invention is configured to include a flange assembly fixed to an inlet of a fuel tank and a reservoir body assembly disposed in the fuel tank, wherein the reservoir body assembly includes: a filter that removes foreign objects included in the diesel fuel; a fuel pump that forcibly circulates the diesel fuel passing through the filter to a diesel engine; and a pump connection return passage that supplies fuel toward a diesel engine through a supply line of fuel but supplies the diesel fuel that is returned without being consumed by the diesel engine between the filter and the fuel pump to supply the fuel to the fuel pump without passing through the filter.
