Generic rubber vacuum hose can be substituted for the pcv valve line assembly, but it will have a rather short life with heated oil gases flowing through it. The factory OE setup has a very short length of rubber tube at each end with a molded plastic tube in between.

United States Patent 6390080 - Intake manifold with a heated PCV passage
In very cold climate conditions, there can be a freeze up in the connection of the PCV hose with the intake manifold. To alleviate possible conditions of freeze up, some PCV systems have a fitting that is heated by engine coolant at the point of intersection between the PCV hose and the manifold.


PCV System Monitor - 2003 MY OBD System Operation Summary for Gasoline Engines
Ford plans to comply with the PCV monitoring requirements by modifying the current PCV system design. The PCV valve will be installed into the rocker cover using a quarter-turn cam-lock design to prevent accidental disconnection. High retention force molded plastic lines will be used from the PCV valve to the intake manifold. The diameter of the lines and the intake manifold entry fitting will be increased so that inadvertent disconnection of the lines after a vehicle is serviced will cause either an immediate engine stall or will not allow the engine to be restarted. Some vehicles will incorporate such designs beginning in the 2001 MY. In the event that the vehicle does not stall if the line between the intake manifold and PCV valve is inadvertently disconnected, the vehicle will have a large vacuum leak that will cause the vehicle to run lean at idle. This will illuminate the MIL after two consecutive driving cycles and will store one or more of the following codes: Lack of O2 sensor switches, Bank1 (P1131 or P2195), Lack of O2 sensor switches Bank 2 (P1151 or P2197), Fuel System Lean, Bank1 (P0171), Fuel System Lean, Bank 2 (P0174)
