Didn't work for me either. I left the engine feed side of the filter disconnected and tried this expecting fuel to begin spewing after a few seconds. It never happened.
Worst comes to worst, I would suggest everyone at the very least pinch the line feeding the engine with a set of locking pliers before completely slipping it off the supply side of the filter.
My 2011 fired up after about 15 seconds of cranking after replacing the filter.
