You definitely don't want to 'crank it up' empty.... There is a thread already going somewhere here about that exact question. Depending on the year, the fuel pump will cycle with the key (13s, I believe - not your 12). The issue was whether the fuel/PS/etc. poured into the housing gets filtered or not. If I read the threads correctly, the PS would get run through the engine unfiltered.
Of course - VCDS will cycle the pumps for you to purge the air, but it can be done with a jumper in the fuel pump relay instead. There is a how-to posted somewhere if you search for it.
