A system for providing downhole chemical injection to at least a first location while also providing power and/or communication between a tool or sensors located below the first location. The system includes a capillary tubing encasing an inner data cable or second capillary tubing while providing sufficient clearance between the data cable or second capillary tubing and the inner wall of the capillary tubing so that fluid may pass through the first capillary tubing to at least a first location while the data cable may pass through to at least the first location or may pass through and below the first location to a tool or sensor package below.
