Modular low profile in tank filter element assembly

A bypass valve for an inside out flow filter assembly comprising:

• a bypass seat with a universal alignment and coupling structure around a bypass central opening, including coupling clips configured to engage with an adjacent universal alignment and coupling structure, a clip ridge configured to receive and engage with coupling clips of an adjacent universal alignment and coupling structure, and a seal receiving surface configured to receive a seal around the bypass central opening and between the adjacent universal alignment and coupling structures, and wherein the bypass seat includes a peripheral radial outlet;
• a cup shaped bypass dish closing the peripheral radial outlet of the bypass seat, and having an annular bypass valve operational area upon which pressure within the filter assembly acts on the bypass dish to move the bypass dish from closing the peripheral radial outlet;
• a bypass cover;
• and
• springs that act upon the cup shaped bypass dish biasing the bypass dish toward closing the peripheral radial outlet of the seat.
