To remove the part of broken screw inside i've nailed a thin screwdriver to the teflon part stuck inside and turn it to unscrew with a bird peak pliers or you can use a cutter or something like to cut it out. One was really stuck and i had to cut using a 1,5mm flat-head screwdriver
Fixed!
ok so i did fix the coffee maker cuisinart EM-200, i removed the teflon screw broken from the pump
as the one i found was too big and didn't fit in the spot of the broken one, i used a compressor piece i think made of brass i had to remove some brass from the hole as the 4mm tube didn't...
