A gaseous fuel injector assembly (fig.2,10) comprising an inlet (fig.3,34) and an outlet 50. The injector has an injector unit (fig.1,20) comprising an injector housing (fig.1,22) and a valve assembly (fig.1,24) and a seating member 52. The seating member comprises a seat body 40, a valve seat 42 and at least one foraminous filter region 48 disposed between the inlet and the outlet wherein the at least one foraminous filter region is integral with the seat body. The injector may comprise first and second circumferential seals (fig.3,54,56) which define an axially-extending sealed space in which the filter region may be wholly defined. The filter region may have a reduced radial thickness compared to the seat body. The seating member may comprise a plurality of filter regions that are equi-angularly spaced around the circumference of the seating member, and may be separated by extending struts 64. Methods of manufacturing a seating member and a gaseous fuel injector assembly are also claimed.
