Abstract: A fluid drain off system for a fuel filter, the system comprising a float, movable together with a trigger device for a switch, such as a magnet, in response to the level of fluid contaminant, a switch arranged to be selectively triggered by the trigger device upon the fluid contaminant reaching a predetermined level, and a fluid passage configured to be selectively opened in response to the triggering of the switch to allow fluid contaminants to be drained from the filter.
