ABSTRACT:
A totally enclosed fuel oil filter housing having a fuel inlet nipple and a fuel outlet nipple is assembled on a mounting bracket with the nipples extending through hexagonal apertures in the mounting bracket. The inlet and outlet nipples are threaded to couple connecting fuel lines and are of different sizes to prevent a reversal of the connections. The nipples have hexagonal peripheries which mate the apertures so that torsional forces during coupling are transmitted to the bracket rather than to the seals between the nipples and the filter housing, and the apertures of the mounting bracket are formed by being drawn out of the plane of the base of the mounting bracket to project therefrom. The side walls of the housing has inwardly directed ribs and a bead of sealant spans each rib to localize the pressure between the side walls of the housing and the accordion pleated filter medium through the sealant bead to assure a void-free seal therebetween.
