Hello

aluminium particles must be from the main fuel pump

I'd 1st say replace the filter and then measure the fuel pressure at the injectors as this will confirm if the pump needs replacing or not

be prepared to have to do this and possibly the injectors too as they may also have been damaged

sorry its not better news
