"follow your fuel line. should
"follow your fuel line. should go from tank, to filter, to fuel pump. filter should be on vacuum side of pump. to drain, loosen the thumbscrew on the bottom of the lower bowl.(engine off) use a bowl or watever to catch water/fuel.(a few ounces is all) to replace, unscrew like an oil filter. there will be some spillage, so plan for it. bowl unscrews from bottom of filter in same fashion. best to remove from boat, and drain first. put bowl on new filter, oil gasket, and thread back onto filter head. there should be no pressure involved."
