  • Fuel filter apparatus and the method of manufacture
    Patent number: 4702790
    Abstract: A fuel filter includes a housing made of plastics and having a main housing portion accommodating a filter element, and a cover. The housing portions are tightly connected to each other at a single ring-shaped glue spot. The housing portion is formed with a pocket filled with glue and the cover is formed with a collar partially projecting into the pocket to form an annular Z-shaped gap in which the glue is distributed. When the glue is solidified the housing and the cover become rigidly and tightly connected to each other. The shape of the gap protects the glue against aggressive fuel.
