thanks to everyone that posted info on this topic. i was able to inspect the fuel module and determine it needed replaced. great thing about this part is it is on back order and nobody in my area even has one. i was told part number 5L8Z9D370A from the expedition will plug in and work but won't mount on the cross member. hoping somebody can tell me if i'm correct because if it doesn't then my 06 f150 is dead. thanks, alex
