Internally mounted/externally accessible fuel supply unit for a fuel sump

摘要

A fuel supply system including a filter removably securable within a filter housing mounted within a fuel tank and a pump removably securable within a pump housing mounted within the fuel tank and interconnected by a pipe. The filter housing includes an inner housing rotatably mounted within an outer housing. Alignable inlet openings and outlet passageways are formed in the inner and outer housings. A removable plug for closing an access opening to the inner housing includes lugs for engaging mating recesses in the inner housing such that rotation of the plug rotates the inner housing relative to the outer housing for rotating the inner housing between an aligned and misaligned orientation relative to the outer housing to control the flow of fluid through the filter housing.
