1997 Mercury Grand Marquis PCV has two Vacuum hose connectors??

This question is answered

My 1997 Mercury Grand Marquis PCV connector has two ports for two vacuum hoses.  The top connector is missing the hose.  I want to replace the hose but can't find were to run the replacement hose.

 

Does anyone know where the missing hose is supposed to go?

  • Some aftermarket PCV valves have two ports, in your case the top port is capped off with a vacuum plug. In other models the top line is used for the EVAP system. Check to make sure you have the correct PCV valve installed on your car.
