The part number simply doesn't exist.
Do you remember which hoses you had to replace? Any guidance on their location would be great. I know of the vacuum hoses coming off the boost solenoid but not sure of the other's that will lead to the exhaust valve solenoid.

Thanks!
The other port in the valve cover (not boost solenoid) goes to the driver's side strut tower and then connects to a vacuum hose that runs all the way to the exhaust flap actuator in the trunk. I only needed to replace the short hose (valve cover to strut tower). Check if there's any enigne oil in the hose. If yes then your vacuum pump is pumping up oil. It happened to me and my valve cover vacuum chamber was filled with engine oil.
