Ah, got it. I'm at a loss then. Perhaps fill the tank and while at idle see if there are any drips under the truck. Maybe a softline (not sure if the e53 has any) finally cracked and leaked a bunch? I had that problem in a couple of e30's with the softlines around the fuel filter.
After that, I'm out of suggestions.

Good luck.
EDIT: BTW, this thread title immediately took my back to my childhood and the Hardy Boys/Nancy Drew series' of books.
