Where to find stainless braided lines

Yes, I thought of that as well. But if the system is fully sealer then won’t there be constant “pressure” once the initial air pocket is removed (taking into consideration I don’t run it dry). And would i be better off mounting the pump in the back so it pushes, or in the front so that it pulls? I’m thinking it will have less of a pressure issue if the pump is closer to the injection point.

Either way, I have the Aquamist DD3S flow system so I immediately know if I lose flow.
