A fuel filter for engines of automobiles comprising a closed casing, a filter element in the casing, a fuel inlet pipe extending through the wall of the casing and opening in the casing for introducing the fuel to be filtered into the space around the element, and a fuel outlet pipe extending through the wall of the casing and opening within the filter element at a level lower than that of the opening of the fuel inlet, the said fuel outlet pipe being formed with a small by-pass opening in the upper portion of the wall of the fuel outlet pipe extending in the filter element, so that the water content of the fuel when accumulated and frozen in a cold season will not clog the fuel inlet of the filter, and that sufficient fuel supply for a cold start of the engine will be ensured through the said by-pass opening.
