And, here's a picture of mine:

It has three hoses. One is shown removed here on my M54 which goes from the F connector to the sucking jet pump.

If you have a simple layperson's explanation for how the sucking jet pump works, I'd be interested in the story.

PS: To the OP: What exactly was the problem you identified?
Blue, it has not yet been confirmed but I can hear air right at the jet pump and the line I noted in the diagram. Just by giving it a small turn I can hear the noise go away. That is what I am hoping.

As for the function Check out post #4
