Fluid filtration systems and methods for servicing thereof are disclosed. The fluid filtration system includes a filter cartridge, a fluid transfer pump, and a valve assembly that can be selectively operated and positioned to achieve a normal filtration mode of operation, a fuel drain mode of operation, and a water drain mode of operation. In the normal mode, the filter cartridge is in an installed position, the pump is rotated in a first direction, and the valve is placed in a first position. In the fuel drain mode, the filter cartridge is in a service position, the pump is rotated in a second direction, and the valve is placed in a second position. In the water drain mode, the filter cartridge is in an installed position, the pump is rotated in the second direction, and the valve is placed in the first position.

Systems and methods for servicing a fluid filtration system

A fluid filter cartridge has a first filter element and a second filter element. The first and second filter elements are arranged consecutively along a longitudinal extension of the fluid filter cartridge. The first filter element has two opposite end faces, one of the end faces being covered by a connection end cap and the other end face being covered by a first end cap. The second filter element has an end face being covered by the connection end cap and another end face covered by a second end cap. At least one port is at the connection end cap in fluid communication with at least one of the first filter element and second filter element. A central axis of the connection end cap orthogonal to a main extension plane of the connection end cap is offset in relation to a central axis of the first end cap orthogonal to a main extension plane of the first end cap and/or a central axis of the second end cap orthogonal to a main extension plane of the second end cap.
