A method and a system for control of a low-pressure circuit in a fuel system of a vehicle, which circuit is arranged to provide the vehicle's engine with fuel from at least one fuel tank via a pressure change system. The system includes a determination unit to make a determination of a future working point for the engine. The determination unit bases this determination on information about a section of road ahead. The system also has a pump operating unit which operates at least one controllable fuel pump which is part of the low-pressure circuit. The pump operating unit bases this operation on the future working point.
