sorry for the delay, busiest time of year at the shop.
I requested a diagram straight from the ford dealer, with your VIN.
it doesnt look like yours with the triple tube fuel filter.
I have included it for you to have a look at.
as for why... i cant answer, this is straight from ford with your vin give. This is all of the documents that I think you will be able to find.
so... I think you have to options to figure out your line system
IT looks like you will have to get creative to match your lines.
My recomendation is to go to the wrecking yard and ask for a "complete fuel line" system including the fuel filter. or if they let you, have a look around the scrap yard and take a few pictures of the system. I think this is the best way to go
i have included another pic of your fuel filter and if you notice that the one line is just a little smaller than the other, this one goes in the middle, while the slightly larger one is of to the side. there is always a slightly larger tube for identification purposes.
I dont think there will be anymore information available, unless you go bug your local dealer for mercey, lol.
my shoes i would hit the scrap yard and pick a whole new line system up.
