According to the present invention, an edge filter for a pressurized fuel rail system having a plurality of fuel injectors from which pressurized fuel is fed to the injectors through a fuel inlet tube is disclosed. The edge filter has contoured leading and trailing ends that may be either spherical or conical to reduce turbulence in fuel upstream and downstream of the edge filter. The edge filter has inlet and outlet slots that are sloped between about 5% and 15% with the depth of the inlet slot decreasing as it approaches the outlet end and the depth of the outlet slot increasing as it approaches the outlet end.
