So I am wondering about my fuel water separators. I have the clear plastic drain bowls on the bottom which are black so I have been trying to loosen them for cleaning and after soaking with penetrating oil for weeks I now have them both loose. But so it now dawns on me, now what? If I drop the bowls for cleaning does the fuel come gushing out? And what is inside the large black housing the bowls are attached to? Also what are the odds that they would need new o rings? Anyone replace these units with newer versions and if so what are they. 

Thanks
Brad
