A filter for use in hydrocarbon fuel system, includes a container (22), having an inlet (52), and an outlet (66), and a filter medium enclosed tightly within the container, this filter medium including layers (32) of alpha-cellulose with interposed layers (34) of an additional medium, whereby a dedicated flow rate can be achieved through the filter for the fuel. A bypass (56) may be provided and this can be actuated by a vacuum sensor switch (68) operational on a solenoid valve (70, 72) to provide a through passage between the inlet (52) and the outlet (66), at the same time an alarm (76) being activated.
