Fuel accumulator having a filter

An apparatus for supplying fuel to a plurality of injectors of a combustion engine or the like, comprises rail means (12) having an inlet (16a, 18a) for the supply of fuel into the rail means and at least one outlet (16b - 16e, 18b-18e) for the delivery of fuel to the injectors. The rail means (12), in the form of a common rail, includes filter means (22; 42) for collecting and/or filtering particles carried in the fuel. The filter means (22; 42) is non-removably disposed within the rail means (12) and arranged so that an opening (26a; 44) thereto aligns with the inlet (16a, 18a) to the rail means (12).
