High Pressure fuel pump filter

Could any pls help, I downloaded a news letter from mitsubishi and they have given a part number MD619968 and the local and regional dealers cant find the part in their systems. This is supposed to be tiny little screw filter for the high pressure pump

That is for a European Diesel engine.

Thanks for your quick response, however, the newsletter refers to CK-6G7GDI which is the petrol motor. The filter is not so much like the filter we know, it is a little screw or needle like. Pls follow the link above

looking at other trends, a lot of people have replaced the pump unknowing about this filter
