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.
