Chances are slim that the banjo is leaking, unless you recently fiddled with it.
Chances are quite good that, like Terry says, old fuel lines, drain valve o-rings, or the bowl heater o-ring, lift pump, etc are leaking. They all drain to the same place - the valley. Do them all at once and save yourself the questionable bonanza of doing it twice.
The ultra low sulfur diesel wreaks havoc on the old o-rings. Bob at diesel o-rings can fix you up if you don't want to have a detached and glassy-eyed Ford parts guy looking at you like you were Dracula himself.
I have found the cheap fuel lift pumps from the O'Reilly's and Autozones of the world aren't worth the effort. Spend the $130 or so, and get the Navistar pump if you are going to keep the OE fuel system. It has a diaphragm that that is more tolerant of the ULSD.
