Abstract
A filter unit for an inlet tube of a fuel injector is shown. The inlet tube has an inside surface, an outside surface, and an annular end surface extending between the inside and outside surfaces. The filter unit includes a filter mesh defining a flow area. A body directs fuel flow through the flow area. The body has a first portion adapted for overlying the inside surface, a second portion adapted for overlying the annular end surface, and a third portion adapted for overlying the outside surface. A ferrule reinforces the body. The ferrule has a first part contiguously engaging the first portion of the body, a second part contiguously engaging the second portion of the body, and a third part contiguously engaging the third portion of the body.
