What General said, they should have used the word drain. You open the drain and use the pump to pump out the water/fuel sample from the bottom of the filter bowl. That is actually one way to confirm if your bypass flapper is sealing. If you open the bottom drain, nothing should happen except a little fuel may dribble out. If it sucks in air and you hear it bubbling up into the filter housing, that is the bypass leaking and the fuel in the fuel line flowing back to the tank creating suction to suck air up into the filter…
