Abstract
A delivery device for a chemical additive is provided for an oil filter. A carrier supporting a chemical additive is arranged within a central opening of a pleated filter media. The carrier interlocks with a center tube, also arranged within the central opening, that supports that filter media. The carrier includes fingers that axially and radially locate the carrier to prevent movement of the carrier within the filter.
