A filter element adapted to removably engage a filter head having an inlet and an outlet, the filter element comprising: an outer housing; a filter cartridge non-removably secured within the outer housing, having: an open end cap defining a central aperture; a closed end cap; and a tubular ring of filter media extending axially along a longitudinal axis between the open and closed end caps and around the longitudinal axis, and defining an inner cavity, and further defining an outer cavity between the outer housing and an outer periphery of the filter media, wherein an inlet side of the filter element comprises the outer cavity, and an outlet side of the filter element comprises the inner cavity; a baseplate having a one-piece construction, non-removably secured within the outer housing and permitting flow between the inlet and the inlet side though at least one inlet port; a first seal retained between and sealing the open end cap to the baseplate to prevent fluid from flowing between the inlet and outlet sides by bypassing the filter media; a second seal retained by the baseplate configured to seal with a first sealing surface of the filter head; and arranged to prevent fluid communication between the inlet side and outlet side; and a third seal retained by the baseplate configured to seal with a second sealing surface of the filter head, the third seal being adapted to limit fluid communication between the inlet side and an exterior of the outer housing when the filter element is installed on the filter head, wherein the baseplate is comprised of a first flow opening, the first flow opening extending axially through the central aperture of the open end cap being in fluid communication with the inner cavity and defining the outlet side therewith, wherein an outer peripheral surface of the first flow opening provides a sealing surface for the first seal, wherein the baseplate is further comprised of at least one inlet port, a seal mount portion, and an outer mounting portion configured for removably engaging the filter head, and a retainer portion adapted to non-removably secure the filter cartridge within the outer housing, characterised in that the seal mount portion extends axially away from the open and closed end caps, and defines a radially outwardly opening groove adapted to axially retain and radially support the second seal. an outer housing; a filter cartridge non-removably secured within the outer housing, having: an open end cap defining a central aperture; a closed end cap; and a tubular ring of filter media extending axially along a longitudinal axis between the open and closed end caps and around the longitudinal axis, and defining an inner cavity, and further defining an outer cavity between the outer housing and an outer periphery of the filter media, wherein an inlet side of the filter element comprises the outer cavity, and an outlet side of the filter element comprises the inner cavity; an open end cap defining a central aperture; a closed end cap; and a tubular ring of filter media extending axially along a longitudinal axis between the open and closed end caps and around the longitudinal axis, and defining an inner cavity, and further defining an outer cavity between the outer housing and an outer periphery of the filter media, wherein an inlet side of the filter element comprises the outer cavity, and an outlet side of the filter element comprises the inner cavity; a baseplate having a one-piece construction, non-removably secured within the outer housing and permitting flow between the inlet and the inlet side though at least one inlet port; a first seal retained between and sealing the open end cap to the baseplate to prevent fluid from flowing between the inlet and outlet sides by bypassing the filter media; a second seal retained by the baseplate configured to seal with a first sealing surface of the filter head; and arranged to prevent fluid communication between the inlet side and outlet side; and a third seal retained by the baseplate configured to seal with a second sealing surface of the filter head, the third seal being adapted to limit fluid communication between the inlet side and an exterior of the outer housing when the filter element is installed on the filter head, wherein the baseplate is comprised of a first flow opening, the first flow opening extending axially through the central aperture of the open end cap being in fluid communication with the inner cavity and defining the outlet side therewith, wherein an outer peripheral surface of the first flow opening provides a sealing surface for the first seal, wherein the baseplate is further comprised of at least one inlet port, a seal mount portion, and an outer mounting portion configured for removably engaging the filter head, and a retainer portion adapted to non-removably secure the filter cartridge within the outer housing, characterised in that the seal mount portion extends axially away from the open and closed end caps, and defines a radially outwardly opening groove adapted to axially retain and radially support the second seal.
