If it ain't broke... don't fix it (bg). What you have is the way it is supposed to be. The line goes to the vacuum proportioning valve on the injection pump. The device is a controlled vacuum leak. Its purpose is to take the high vacuum made for the brakes and leak it off to the appropriate value to correspond to the various throttle positions. If the device just sucked out the side of the valve it might pick up all kinds of trash from the engine compartment. By running the line into the dash it sucks clean air.
