Do you have a link for the tool?I took mine apart and dumped it out. Then pumped it many times to get out the rest. You have to take the 2 sections of the fork apart, so I don't think compressing with a strap would work. But I don't know for sure. Buy the tool it is only $40.
BTW: Replace your seals while you are in there.
