Abstract
A rechargeable spin-on filter includes a cover, a housing threadably joined with the housing, and a filter element that can be removed and replaced with another filter element relative thereto. The cover and/or housing can be plastic. The cover can include a bottom plate having inlet ports and an outlet port. The filter element can include an end cap defining a perimeter about an inner dimension, such as an inner diameter. The cap can define a groove to receive a rib of a support tube over which the element is installed. Alignment of the rib and groove can index and register the element with the support tube. A related method is provided.
