In general, a connector tube is a fluid-carrying line used to link one hydraulic or fuel-system point to another, and a main relief is a pressure-limiting device that protects a system from excessive pressure. The exact role of this connector-tube assembly, including what it connects and which components it serves, must be checked against the catalog.
