Power Steering Filter for 84-91 Vanagon

Located inside the power steering fluid reservoir this filter should be replaced whenever you are replacing the power steering rack or hoses. You have to unscrew the large black cap off of the reservoir and then remove the large spring and white plastic piece that is on top of this filter. It sits in the very bottom of the reservoir and you can't see it unless you remove these other parts from above. This is the filter only. Not sure what that other ring looking thing in the picture is, but that isn't included.
