The assembly includes a reserve tank and a fuel pump mounted within the reserve tank with a noise dampening cylindrical intermediate layer.

A vent channel is provided bypassing the intermediate layers and connecting the intake chamber with a vent conduit for venting gases from the intake chamber of the fuel pump.
