Abstract
A liquid filter unit can be used to filter fuel and includes a ball which is moved into a position to prevent further fuel flow through the filter unit when a predetermined amount of water is collected in the unit. One form of the unit includes a water soluble membrane anchoring the ball in place. This form of the filter unit can be used in either the vertical or horizontal orientation, and can be used for high fluid flow rates.
