strip down, no problem. There is a circlip at the end of the injector.
Take that one off, push the injector up the tube. If there is a filter
at the end (part no. ends with d) that falls away and can be cleaned.
Then you will see, that the end of the injector is a white plastic
tingy, that fits an allen key. undo this end and the injector falls sort
of apart. The valve can be lapped in with needle lapping stuff.
Refitting is the reversal of removal <grin>
