water seperator leak. 2008 6.4l
 

i have had this gallon a day plus fuel leak. i thought i had trash in the water seperator valve. so i worked it and one of the torx screws head fell into my fuel catching bucket. can i fix this thing. where are the screws located? do i need a whole new seperator? if i can get the valve body off, how do i remove the screw? any help is greatly appreciated. thanks mucho! mark
