It sounds to me like you already installed the kit correctly.
The extra line does replace the OEM hard line running between the port on the back of the head and the AVCS port.
With the filtered kit in place I personally would remove the screen from the banjo bolt.
One more thing, if using stock IHI turbo, you need to install tbe same restricted flow banjo bolt that was originally instaled at the turbo. The new oil line kit removes all oil flow restrictions.
