draining racor procedure

put a racor on my 06/250 hpdi last year when I bought it. Figure it might me time to drain it before new season. do u spin the entire base off or I see what seems to be a vent screw on the bottom. Dont wont to make something simple --complicated if I dont need to http://www.bassboatcentral.com/smileys/roll.gif

If you have the one with the clear bowl you should be able to see any water in there. The water will settle to the bottom since it is heavier than gas. If you want to drain it anyway....just turn the valve counter clockwise.
