A preferably fiber optic line passes into a well interior through a pressure barrier such as a tree or wellhead housing, via a modified horizontal penetrator assembly. The penetrator assembly comprises double poppet valve assemblies arranged to open upon engagement of the penetrator with an interior well component such as a tubing hanger. Retraction of the penetrator closes the poppet valves, sealing the pressure barrier, severing the line and allowing the tubing hanger to be pulled. A replacement line is readily installed through the open poppet valve assemblies.
