Claim:
A filtration system comprising: at least two filters mounted adjacent to each other, each filter comprising: A) a canister extending along a longitudinal axis; B) a closed end cap at one end of the canister attached to the canister for closing one end thereof; C) a filter element contained within the canister; and D) a modular one-piece input end cap for attachment to the canister, the one-piece input end cap comprising: i) a mounting portion including a cylindrical member for attachment to the canister; ii) a hydraulic input chamber extending to the filter element in the canister, said hydraulic input chamber being kidney shaped as viewed in a direction parallel to said longitudinal axis and is configured to be ported in any of three mutually perpendicular directions including one direction parallel to said longitudinal axis; iii) a hydraulic output chamber extending from the filter element in the canister, wherein the hydraulic output chamber is kidney shaped as viewed in a direction parallel to said longitudinal axis and is configured to be ported in any of three mutually perpendicular directions including one direction parallel to said longitudinal axis; iv) bosses on two opposed sides of the modular one-piece input end cap, one boss configured to allow for the placement of a hydraulic port there in extending to the hydraulic input chamber and the other boss configured to allow for placement of a hydraulic port there in extending to the hydraulic output chamber; and v) mounting flanges on two opposed sides of the modular one-piece input end cap, each mounting flange extending the entire width of the modular one-piece input end cap between the opposed sides containing the bosses, one flange configured to allow for the placement of a hydraulic port there in extending to the hydraulic input chamber and the other flange configured to allow for the placement of a hydraulic port there in extending to the hydraulic output chamber.
