Abstract
A fuel filter, such as a filter for filtering gasoline or diesel fuel to be supplied to an internal combustion engine, includes an annular main filter element through which fluid to be filtered can pass radially, and a supplemental fluid processing element disposed within the main filter element to which fluid discharged from the main filter element passes. The filter also has end caps, between which opposite ends of both the main filter element and the supplemental fluid processing element are disposed, and to which the opposite ends of both the main filter element and the supplemental fluid processing element are secured. Fluid is discharged from a central volume of the filter through one of the end caps.
