In a fuel-water separator including entry and exit ports for fuel connectable in a fuel line supplying an engine and fuel flow paths between the ports for separating water from the fuel, the improvement comprises first and second passages leading to the exit port and a float valve ball for closing the first passage in response to the accumulation of a predetermined level of separated water. The second passage has a cross-sectional dimension which is substantially smaller than the first so that only restricted operation of the engine is permitted by virtue of a reduced fuel flow rate through the second passage when the first passage is closed.

A fuel-water separator comprising a container, an inlet to and an outlet from the container, the inlet and outlet being connectable in a fuel line supplying an engine, a pair of passages leading to the outlet, a first of which is much larger than the second, means inside said container defining a progression of spaces through which the fuel moves from the inlet to the outlet, said space-defining means being disposed in said container to direct the fuel through a series of downwardly and upwardly directed paths as it moves through said spaces to cause the higher density water to move downwardly while the lower density fuel moves upwardly, said space-defining means further defining openings in the lower portions of said spaces through which the separated water drains downwardly, first valve means for closing at least one of said openings to control the fuel and water movement, and second valve means actuable by a predetermined amount of water in the container for closing said larger passage whereby only restricted operation of said engine is permitted by virtue of the fuel flow rate through said smaller passage.
