Passenger Side Fuel Line Part #

[06F350xl]

The fuel line running from the filter housing on top of the motor down to the passenger side is leaking. I have called 3 different dealerships to order the new line and none of them have it in stock, so I have to pay before they order it. The only problem I have is that all three dealerships have given me different part numbers for what should be the same line. Does anyone happen to know where I can find a decent blow-up diagram or the part number for this line?

or maybe some of you dealers reading this have an aftermarket solution for me that won't break the bank? It is a mostly stock truck with 210,000 miles on it. I got a 4" turbo back exhaust (no cat), cold air intake, rebuilt 03 turbo and run SCT tuner. I use it as a daily driver and on the weekends pull a 4 horse trailer so I don't need anything to crazy.
