I just purchased an RDS 60 gal aux tool and fuel tank for my bed of my 04 2500HD Duramax, I set it up with the install kit from northern tool that requires you to run the drain line to tap into the main fill line with an adapter. When I cut through the main line to add the adapter I cut a plastic insert inside the main rubber fuel fill line. Is this plastic piece needed, what does it do? Also does anyone know what the return and withdraw plugs are for on the top of the tank. I only used the drain plug to connect my manual shutoff valve to T into the main fill line with the aluminum T provided.

Thanks in advance for the help, I am a little green in the aux tanks as you can see.
