To my fellow Viking ... I was in the same boat a few months back. My fix was chronicled (with lots of pictures - I love the pix!) here.
Garth 's step-by-step process will take you where you need to go ... however, I suggest merely blowing through the vacuum line (into your fuel cell) BEFORE attempting to use a compressor. I was able to blow the "sock" off myself. As soon as you hear the gas bubbling, you know you have no worries with the vacuum side of your fuel line. Then turn your attention to the pump itself and the pressure line (with a new inlet filter).
