A filter element disclosed herein includes a center tube defining a central reservoir and including an interior sidewall. The filter element further includes an end plate and a pocket defining a port extending from the end plate into the central reservoir. The pocket includes an inner wall, an outer wall, and a plurality of projections extending from the outer wall of the pocket toward the interior sidewall of the center tube.

Canister filter system with drain that cooperates with filter element

An endcap including a first plate member including a radial inner portion, a radial outer portion, and defining a longitudinal axis. The endcap also includes a flange disposed between the radial inner and outer portions of the first plate member and projecting axially along the longitudinal axis in a first direction. The endcap also includes a first seal member disposed adjacent the flange. The first seal includes a first portion thereof engaged with an axial facing surface of the first plate member and a second portion thereof engaged with a radially facing surface of the flange. The endcap further includes a second plate member disposed radially outward of the radial outer portion and a second seal member disposed adjacent the second plate member including at least a portion thereof axially spaced from the axially facing surface of the first plate member in a second direction along the longitudinal axis opposite the first direction.

Fluid filter system

A canister filter system includes a base, a canister attachable to the base, and a fluid separator filter having filter media positioned inside the canister. A drain engages and forms a seal with the filter in a closed position. In an open position, the drain allows fluid to be removed from the canister. The structure of the filter is such that the filter may more efficiently separate fluids.

Filter system with fuel-water separator

An endcap includes a first plate member having a radial inner portion, a radial outer portion, and defining a longitudinal axis. The endcap also includes a flange disposed between the radial inner and outer portions, and projecting axially along the longitudinal axis in a first direction. The endcap also includes a first seal member disposed adjacent the flange. The first seal member includes a first portion engaged with an axial facing surface of the first plate member and a second portion engaged with a radially facing surface of the flange. The endcap further includes a second plate member disposed radially outward of the radial outer portion and a second seal member disposed adjacent the second plate member including at least a portion axially spaced from the axially facing surface of the first plate member in a second direction along the longitudinal axis opposite the first direction.
