Abstract: An all-plastic filter assembly (250) for filtering fluids includes a generally cylindrical injection molded plastic outer shell (251) which has a closed base and an open opposite end and which defines a hollow interior which receives a modular filter cartridge (263). The outer shell is injection molded with a generally cylindrical mounting stem (259) which is integral with the closed base and extends part way toward the open end of the outer shell. The filter cartridge includes a generally cylindrical filter element and a molded end plate (265) and center tube member (274) bonded to the filter element. The center tube portion of the molded member is received by the mounting stem as a part of the positioning and mounting of the filter cartridge into the outer shell.
