ABSTRACT:
A marine water separating fuel filter includes a connecting tube head, an upper lid, a filter element, and a container. The filter element is accommodated in the container and sealed by the upper lid, with an axial inlet opening and a limiting ring provided on a hollow taper post to hold against the filter element. An axial pipe of the connecting tube head is screwed to the axial inlet opening. The connecting tube head has a pressing ring to hold against a washer, providing a sealing function. The unfiltered fuel from an inlet end is filtered with the filter element and then filtered fuel expelled through an outlet end. An indication ring is provided on the hollow taper post to indicate the height of liquid. This is an easy and quick way to assemble and disassemble the filter element, providing environmental and economical purposes.
